Jehbco Silicones Extrusion Tolerances – Precision Through Quality Control

Quality control is central to Jehbco’s approach to silicone extrusion. As a supplier to customers in medical and Defence applications, including naval, land and aerospace programs, Jehbco understands that silicone components are often required to perform in demanding environments where consistency, fit and reliability are critical. In these applications, dimensional accuracy can directly affect sealing performance, assembly efficiency, service life and the reliability of the final system.

For this reason, Jehbco places strong emphasis on controlling extrusion tolerances. Customers often require silicone profiles that exceed general industry tolerance classes, particularly where components are used in specialised equipment, regulated industries or critical operating environments. As shown in our tolerance chart below, Jehbco’s silicone extrusions are made to tolerances tighter than ISO 3302-1 Class E1, the industry gold-standard, across every listed nominal dimension range for cross-sections of solid extrusions.

Table 1. Comparison of tolerances of solid extrusion cross-sections as specified by Jehbco Silicones and ISO 3302-1 Class E1 and Class E2.

This table demonstrates the company’s commitment to precision, consistency and high-quality silicone extrusion manufacturing.

Why Tight Tolerances Matter

Silicone extrusions are used in many applications where dimensional consistency is essential. A seal may need to compress evenly in a groove. A tube may need a controlled internal diameter and wall thickness. A gasket may need to fit cleanly into a housing without gaps, distortion or excessive installation force. In each case, small dimensional variations can affect performance.

This is especially important in medical and Defence applications, where silicone extrusions may form part of a larger assembly with strict design requirements. A profile that is too large may be difficult to install or may create excessive compression. A profile that is too small may not seal effectively. A wall section that varies too much may affect strength, flexibility, pressure resistance or service life.

By manufacturing solid silicone extrusion cross-sections to tolerances tighter than Class E1 values, Jehbco helps customers reduce the risk of fitment issues and improve consistency from batch to batch. Tight tolerance control supports reliable assembly, repeatable performance and reduced variation in the finished product.

How Jehbco Achieves Tight Tolerances Through Quality Control

Achieving tight extrusion tolerances requires control at every stage of production. Silicone is a flexible elastomer, and its final dimensions are influenced by compound selection, hardness, profile shape, wall thickness, tooling design, extrusion speed, curing conditions and handling. The material can expand, relax, cure and cool after passing through the die, so dimensional control must be built into the process from the beginning.

For Jehbco, this starts with tooling. The die must be designed to account for how the silicone compound will flow and how the profile will behave after it exits the tooling. The die opening is not simply the desired final shape of the extrusion. It must compensate for material movement, die swell, cure behaviour and the geometry of the profile.

This is particularly important for detailed profiles, thin wall sections, sealing features and parts that must fit accurately into a mating component. Small changes in tooling or process conditions can affect the final dimensions, so tooling design, setup and adjustment are all important parts of producing a consistent profile.

Once production begins, process control becomes critical. Extrusion speed, material feed, temperature, curing conditions, conveyor speed and handling all contribute to dimensional stability. Jehbco controls these variables to maintain consistency throughout production.

Figure 1. Starett VB400 optical comparator used at Jehbco for accurate, non-contact measurements of silicone extrusions.

Throughout production runs, Jehbco regularly takes samples for measurement and continually checks extrusion dimensions to ensure profiles remain within the required tolerance range. These in-process checks are carried out using several methods, including optical comparator inspection for detailed profile measurement and purpose-built test fitting jigs to confirm that mating parts fit correctly. The optical comparator allows highly accurate and precise non-contact measurement of silicone extrusion profiles, including fine details and flexible sections that may not be possible to measure reliably using traditional contact methods such as vernier calipers and micrometers. By checking dimensions during production, rather than only at final inspection, Jehbco can monitor consistency, identify variation early and maintain tight control over the finished extrusion.

This combination of tooling expertise, controlled processing, sample measurement, in-process inspection and final checks supports Jehbco’s ability to manufacture silicone extrusions to demanding dimensional requirements.

Tailored to Customer Requirements

Although Jehbco’s tolerance chart provides a clear comparison against Class E1 and Class E2, many projects also have customer-specific requirements. Some customers may require a profile to match an existing part. Others may need a silicone extrusion to fit into a newly designed assembly. Some applications may require particular dimensions to be controlled especially closely because they affect sealing, retention, compression or flow.

Jehbco works with customers to understand these requirements and manufacture silicone extrusions to suit the intended application. This may include reviewing drawings, discussing critical dimensions, assessing material options and advising on manufacturability before tooling or production begins.

This collaborative approach is particularly valuable for custom silicone profiles. By considering tolerances early in the design and manufacturing process, customers can improve the likelihood of achieving a reliable, repeatable result. Jehbco can also advise when a requested tolerance is practical for extrusion and when design changes may help improve dimensional control.

Supporting Critical Applications

Jehbco supplies silicone extrusions for industries where quality and repeatability are essential. In medical applications, components may need to meet strict cleanliness, material and dimensional requirements. In Defence applications, including naval, land and aerospace systems, silicone profiles may be exposed to demanding operating environments or form part of equipment where reliability is critical.

In these sectors, customers need confidence that the parts they receive will meet the drawing and perform consistently in service. Jehbco’s ability to manufacture silicone extrusions to tolerances tighter than Class E1 supports this need. Whether the requirement is for a seal, gasket, tube, cord, strip or custom profile, each project is reviewed with consideration of the material, geometry, tolerance requirements and application.

Conductive silicone seals in lab environment

Conductive Silicone Seals: Enhancing Protection and Performance

As industries continue to adopt more advanced electronic systems, the demand for materials that provide both environmental sealing and electrical performance is growing rapidly. Conductive silicone seals have become an important solution across sectors such as electronics, automotive, telecommunications, aerospace, and industrial manufacturing.

These specialised seals combine the flexibility and durability of silicone rubber with conductive fillers such as carbon, nickel, or silver-coated particles. The result is a material capable of delivering reliable sealing performance while also assisting with electrical grounding and EMI/RFI shielding.

What Are Conductive Silicone Seals?

Conductive silicone seals are elastomeric components designed to protect sensitive equipment from environmental conditions and electromagnetic interference at the same time.

Unlike standard silicone seals, conductive silicone materials allow electrical conductivity across the surface, helping reduce electromagnetic interference (EMI) and radio frequency interference (RFI). This makes them highly valuable in applications where stable electronic performance is critical.

By combining sealing and conductivity in one material, manufacturers can simplify product designs and reduce the need for multiple components.

Key Benefits

EMI and RFI Shielding

One of the primary functions of conductive silicone seals is shielding sensitive electronics from electromagnetic interference. In modern equipment, unwanted electrical noise can affect performance, communication, and signal reliability.

Conductive silicone helps create a conductive barrier around enclosures and components, improving system stability and protecting sensitive electronics.

Excellent Environmental Resistance

Silicone rubber is known for its ability to withstand harsh environmental conditions. Conductive silicone seals maintain strong resistance to:

  • Moisture and humidity
  • UV and ozone exposure
  • Weathering and ageing
  • Mechanical stress and vibration
  • Extreme temperatures

This makes them suitable for both indoor and outdoor applications.

Wide Temperature Range

Conductive silicone seals perform reliably across a broad temperature range, typically from -60°C to +200°C, with some grades tolerating intermittent exposure to higher temperatures.

The material remains flexible in cold environments while resisting cracking, hardening, and degradation over time.

Flame Retardant Options

For applications requiring enhanced fire safety, conductive silicone compounds can also be manufactured with flame-retardant properties.

These materials are designed to:

  • Limit flame spread
  • Self-extinguish once ignition is removed
  • Produce lower smoke emissions

Depending on the application, materials can be formulated to meet standards such as UL 94 V0 and other industry-specific requirements.

Common Applications

Conductive silicone seals are used across many industries where both protection and electrical performance are required.

Electronics and Telecommunications

Used in enclosures, connectors, and communication equipment to minimise EMI and maintain signal integrity.

Automotive and Electric Vehicles

Commonly used in battery systems, charging units, and electronic control modules where heat resistance and shielding are essential.

Chemical resistance testing in the lab

Chemical Resistance of Silicone Rubber

Silicone rubber boasts one of the most extensive chemical resistance profiles among commercially available elastomer families. This feature, combined with its excellent resistance to heat, UV, ozone and weathering, makes silicone rubber one of the most durable materials for use in construction and sealing applications. Concurrently, its excellent biocompatibility and low toxicity allows it to be used in a variety of food and safety applications as well.

As a predominantly polydimethylsiloxane based polymer, silicone rubber is highly hydrophobic and naturally repels water and polar solvents such as methanol, ethanol isopropanol and mild acids and bases. This hydrophobicity allows it to retain its mechanical and chemical characteristics upon prolonged exposure to these chemicals. While silicone is hydrophobic in nature, it also has good resistance to many long-chain hydrophobic materials such as paraffins and vegetable oils.

Despite excellent resistance to a variety of common solvents and chemical substrates, there are some families of chemicals where long-term exposure should be avoided, some with worse physical effects than others. Most commonly, small molecular weight hydrophobic molecules should be avoided, such as hexane, chloroform and in particular, aromatic compounds such as benzene, toluene and xylene. These chemicals will consistently cause the silicone rubber to swell, resulting in a softer material with significantly reduced mechanical properties. Additionally, contact with all common fuels such as will diesel also result in significant and rapid swelling of silicone articles, and contact with these substrates and their fumes should be avoided.

Additionally, while silicone rubber repels polar substances, it should not be used in contact with strong acids and bases. In moderate concentration, these compounds can catalyse the hydrolysis of Si-O bonds resulting degradation of the material over time. More concentrated solutions can result in other side-reactions with silicone rubber resulting in immediate degradation of the product. Similarly, Si-O hydrolysis can be observed in very long periods of contact with high pressure, high temperature steam. Despite this, typical autoclaving conditions do not usually result in significant degradation of silicone articles, and silicone is commonly used to manufacture autoclave and steam contact seals in a variety of industries.

While these are general trends in silicone chemical compatibility, always perform individual chemical resistance testing on silicone rubber articles with the contact substrate in question. Further detailed recommendations can be found on chemical compatibility charts, including one provided on the Jehbco website.

Shore A Hardness of Silicone Rubber – What It Means and Why It Matters

Shore A Hardness of Silicone Rubber – What It Means and Why It Matters

Figure 1. Sauter Shore A durometer in use at Jehbco Silicones.

When specifying a silicone rubber for an extrusion, gasket, seal, sleeve, or custom profile, one of the first numbers you’ll see is Shore A hardness. It’s often treated as a quick “soft vs firm” indicator, but Shore A hardness influences far more than feel. It affects how a silicone part seals, wears, installs, handles pressure, and maintains performance over time.

This article explains what Shore A hardness is, how it relates to real-world material properties, and how to select the right hardness for different applications.

What is Shore A hardness?

Shore A hardness is a standardised way of measuring the hardness of elas

tomers (rubbers). It is measured with a handheld instrument called a durometer that presses an indenter into the material under a defined force. The durometer reports a value from 0 to 100 based on how far the indenter penetrates: deeper penetration = softer material, and less penetration = harder material. The level of penetration is converted into a Shore A hardness rating where:

  • Lower numbers (e.g., 20A–40A) mean a softer, more compliant rubber.
  • Higher numbers (e.g., 60A–80A+) mean a firmer, more resistant rubber.

Shore A is most commonly used for rubbers like silicone, EPDM, nitrile, and neoprene. Very soft gels may be measured on Shore 00, while very hard plastics are often measured on Shore D (see Fig. 3).

 

 

Figure 2. Indenters of Shore A and Shore D durometers. (Source: https://www.lindeseals.com/news/what-is-shore-a-hardness-78017418.html)

 

Why hardness matters in silicone rubber performance

Hardness is not a direct measurement of strength, but it correlates with several important performance characteristics.

1) Compression and sealing performance

Silicone seals by deforming to fill gaps and maintain contact pressure. In general:

  • Softer silicone (lower Shore A) conforms more easily to irregular surfaces and requires less clamping force to achieve a seal.
  • Harder silicone (higher Shore A) resists deformation and can maintain sealing shape under load but may require higher clamp loads and better mating surface quality.

A hardness that is too soft may extrude out of a joint or lose contact pressure over time. Too hard, and it may not conform well enough to seal at all.

2) Compression set (ability to “spring back”)

Compression set describes how well rubber returns to its original thickness after being compressed for a period. While formulation matters greatly, hardness selection plays a role:

  • Very soft compounds can be more prone to taking a “set” in high-compression static joints.
  • Medium hardness compounds often offer a useful balance of compliance and recovery.
  • Higher hardness compounds can resist permanent deformation, but if they don’t compress enough, sealing can be inconsistent.

For critical sealing, it’s best to consider hardness together with compression set data at the relevant temperature and time.

3) Tensile strength and tear resistance

Hardness does not automatically equal strength, but typical trends include:

  • Moving from very soft to medium hardness often increases tear strength and resistance to nicking during installation.
  • Very hard compounds may resist indentation well but can be more sensitive to sharp notches depending on formulation.

For extrusions that will be stretched, pulled, clipped, or fitted over edges, tear strength and elongation can matter as much as hardness.

4) Abrasion, wear, and surface durability

Harder silicone generally offers improved resistance to surface indentation and can perform better in applications involving sliding contact, minor rubbing, or repeated handling. Softer grades can be excellent for gentle sealing, but may mark, scuff, or wear faster in dynamic contact.

If the part sees repeated movement (e.g., door sweeps, wipe seals, protective sleeves), hardness selection should be aligned with the wear mechanism.

5) Flexibility, handling, and installation

Hardness strongly influences how a silicone extrusion behaves during manufacturing and installation:

  • Lower Shore A profiles are easier to compress and can be simpler to fit into uneven gaps but may be more difficult to push into tight retaining channels without stretching.
  • Higher Shore A profiles can feed and handle more “crisply” and can be easier to install into certain carrier systems but may not tolerate misalignment or variable gaps as well.

For snap-fit designs, barbed profiles, or tight-tolerance grooves, a small change in hardness can noticeably change the “feel” and retention performance.

Shore A hardness and tolerances: why the “fit” matters

In real assemblies, seals must work across tolerance stack-ups—variation in groove sizes, flange flatness, paint thickness, door gaps, and installation alignment. Shore A hardness affects how well silicone can absorb that variation:

  • Softer silicone (lower Shore A) compresses more easily and conforms to uneven surfaces, making it more forgiving when gaps vary. The trade-off is that it can over-compress in tight areas, increasing closure/clamp force and potentially reducing service life if the design doesn’t control compression.
  • Harder silicone (higher Shore A) resists deformation and holds its shape better but typically needs tighter tolerances or higher clamp loads to achieve consistent compression—otherwise it may not compress enough to seal at the “large gap” end of the tolerance range.

For reliable sealing, hardness should be selected alongside the target compression range and the expected minimum/maximum gap. Where tolerances are wide, geometry can help (e.g., hollow bulbs, multi-lip profiles etc.) so the seal remains effective without excessive force.

Typical Shore A hardness ranges for silicone rubber

There is no single “best” hardness. Selection depends on what the part must do.

Very soft (10A–30A)
Used where high conformity is needed: gentle sealing, cushioning, vibration isolation, soft grips, sensitive contact surfaces.

Soft–medium (30A–50A)
A common range for general-purpose seals and extrusions: good compliance with improved handling and tear resistance.

Medium–firm (50A–70A)
Often chosen for robust gasket profiles, higher clamp loads, parts that must resist deformation, and applications where the seal must hold its shape.

Firm–hard (70A–90A+)
Used for parts needing high resistance to indentation and deformation, tight dimensional stability, or more “structural” elastomer behaviour (e.g., bump stops, firm sleeves, certain high-load seals).

 

Figure 3. Comparison chart illustrating the relative hardness ranges of Shore 00, Shore A, and Shore D scales, with representative material examples for each hardness range. (Source: https://amesdirect.com.au/resources/understanding-shore-hardness/)

Application guidance: choosing the right Shore A hardness

Below are typical suitability guidelines. Exact hardness should be validated against joint design, loading, temperature, and tolerance stack-up.

Static sealing (gaskets, flanges, enclosures)

  • 30A–60A is common depending on flange flatness and clamp load.
  • Softer if surfaces are uneven or clamp load is limited.
  • Firmer if extrusion resistance, shape retention, or higher pressure resistance is needed.

Door, hatch, and access panel seals

  • 40A–70A is typical depending on closure force and sealing geometry.
  • Softer reduces closing force; firmer improves durability and shape retention, especially for larger profiles.

Cable grommets and pass-through seals

  • 30A–60A depending on insertion forces and sealing requirements.
  • Softer improves conformity to cables; firmer improves tear resistance during repeated assembly.

Protective sleeves, edge trims, wear strips

  • 50A–80A often preferred for durability and abrasion resistance.
  • Consider surface finish and lubrication if sliding contact is involved.

Vibration isolation and cushioning

  • 10A–40A depending on load, deflection targets, and frequency range.
  • Hardness should be selected alongside geometry (thickness, area, voids) because shape often dominates stiffness.

High-pressure or extrusion-prone joints

  • 60A–90A may be required, often with supporting design features (anti-extrusion lips, back-up rings, tighter gaps).
  • Hardness alone is not a substitute for good gland design.

Important note: hardness is only one part of the specification

Two silicone materials can share the same Shore A hardness yet behave differently because of:

  • Formulation and filler system
  • Tear strength
  • Elongation
  • Compression set performance
  • Temperature range and thermal ageing
  • Media/chemical exposure
  • Colour and additives (e.g., flame retardants, low smoke, antimicrobial, food-grade compliance)

For this reason, hardness should be treated as a starting point. For critical applications, it’s best to review a material’s full datasheet and confirm performance via prototypes or trials.

How Jehbco Silicones can help

Selecting Shore A hardness is ultimately about balancing sealing performance, durability, installation forces, and dimensional stability. Jehbco Silicones manufactures silicone extrusions across a wide range of hardness grades and can assist with:

  • Hardness selection for your joint geometry and tolerance conditions
  • Recommendations to reduce closing force while maintaining seal integrity
  • Material options to improve tear resistance and service life
  • Prototyping and iterative refinement for custom profiles

If you have an application in mind, provide your gap dimensions, mating material, expected compression, movement (if any), temperature range, and exposure environment, and our sales team can help narrow down a suitable Shore A hardness and compound type.

Top 10 Australian Industries Driving Demand for Silicone Extrusions in 2026

Top 10 Australian Industries Driving Demand for Silicone Extrusions in 2026

High-performance silicone extrusions are playing an increasingly important role across Australia’s industrial, manufacturing and infrastructure sectors. As equipment becomes more advanced, buildings more energy-efficient, and compliance requirements more demanding, engineers and procurement teams are placing greater emphasis on materials that deliver long service life, reliability, and consistent performance.

Silicone rubber stands out due to its exceptional temperature stability, UV and weather resistance, chemical inertness, flexibility, and durability. Unlike many conventional elastomers, silicone maintains its properties in extreme environments and under continuous operation, making it an ideal choice for critical sealing, insulating, and protection applications.

The following industries represent the key drivers of silicone extrusion demand in Australia in 2025-2026, and highlight where high-quality, Australian-made silicone extrusions provide the greatest operational and commercial benefit.

1. Construction and Architectural Glazing

The construction and architectural glazing sectors are among the largest consumers of silicone extrusions in Australia. Silicone profiles are widely used for window and door seals, façade gaskets, expansion joints, and fire-rated sealing systems, particularly on exposed commercial buildings and infrastructure.

Market demand in this sector is driven by:

  • rising use of energy-efficient glazing and façade systems
  • stricter National Construction Code (NCC) performance requirements
  • bushfire-resistant construction standards
  • Australia’s high levels of UV, ozone, heat and weather exposure

Silicone is ideally suited to these applications because it retains flexibility across a wide temperature range, resists UV/ozone degradation, and maintains elasticity and dimensional stability in harsh outdoor conditions. This durable performance helps maintain watertight and airtight seals for decades without cracking, hardening or shrinking.

A notable example of silicone applications in this sector is Quickjoint by JEHBSIL, Jehbco’s purpose-engineered solid silicone expansion joint seal designed specifically for architectural gap sealing. Unlike traditional wet sealants, Quickjoint is a pre-cured silicone extrusion that delivers:

  • Guaranteed factory finish on every joint, ensuring consistent quality and appearance without defects at project completion
  • Quick installation, with no tooling off required and no need for specialised caulking skills
  • No early expansion and contraction issues typical of site-applied sealants
  • Colour matching to façade panels and custom sizes to suit project requirements
  • No backing rods, masking tape or clean-up work
  • All-weather installation, including the ability to install even if rain is forecasted

 

Figure 3. Applications of Quickjoint by Jehbsil, a custom engineered solid silicone solution for architectural gap seals.

Figure 1. Applications of Quickjoint by Jehbsil, a custom engineered solid silicone solution for architectural gap seals.

Quickjoint’s solid silicone construction means it is already temperature and weather resistant, and it expands and contracts with a building more reliably than conventional wet sealants. It can be installed in very hot temperatures without specialised labour, saving both time and cost on site and eliminating the installation constraints and mess associated with liquid sealants.

Typical construction applications for Quickjoint by JEHBSIL include:

  • façades and exterior cladding systems
  • curtain wall joints
  • expansion and control joints in precast concrete, marble, granite and timber panels
  • weather sealing of aluminium composite and coated metal panels
  • expansion joints on pavement and podium slabs

By combining silicone’s inherent durability and flexibility with a pre-formed extrusion solution, Quickjoint provides a long-lasting, visually clean and mechanically reliable sealing option that protects buildings from water ingress, weathering, and structural movement more effectively than traditional sealants.

2. Food and Beverage Manufacturing

Australia’s food and beverage industry is large and diverse, covering meat processing, dairy, beverage bottling, commercial kitchens, and potable water systems. Manufacturers typically require food-contact-safe silicone that can withstand heat, frequent cleaning, and continuous operation. Common uses include:

  • clean tubing for liquid transfer and potable water systems
  • oven and equipment door gaskets
  • seals for filling and packaging lines
  • mixers and conveyor equipment

Jehbco supplies high-quality silicone tubing and sleeves that are odourless, tasteless, non-toxic and chemically resistant, making them suitable for hygienic fluid transfer applications, including potable water applications in food and beverage environments. Jehbco’s silicone tubing is made from pure silicone elastomers and can be manufactured in a wide range of diameters and wall thicknesses to suit specific systems, including hot and cold drinking water delivery equipment such as Zip Water HydroTap installations, where reliable potable water-safe tubing is essential for seamless operation and compliance with health standards.

Silicone’s heat resistance and compatibility with cleaning chemicals give it long-term performance advantages in food processing environments. Its flexibility and high-temperature stability also help seals maintain integrity over extended production cycles, reducing downtime and maintenance costs while supporting compliance with hygiene and food safety requirements.

3. HVAC, Refrigeration and Building Services

Heating, ventilation, air conditioning and refrigeration systems continue to be a major source of silicone extrusion demand as Australia focuses on energy-efficient buildings and climate control.

Common silicone applications include:

  • duct and panel gaskets
  • high-temperature seals for heaters and boilers
  • vibration-damping profiles
  • rooftop weather seals
  • refrigeration door gaskets

Silicone performs exceptionally well in HVAC systems because it maintains flexibility in both hot and cold conditions, seals effectively under low compression forces, and resists degradation from UV exposure on rooftops.

Reliable sealing improves system efficiency by preventing air leakage, directly contributing to lower energy consumption and improved building performance.

4. Medical, Pharmaceutical and Biotech

Medical and pharmaceutical environments demand materials with high purity, stability and repeatable performance. Silicone extrusions are widely used in medical devices, laboratory equipment, cleanrooms, and fluid-handling systems.

Typical applications include:

  • tubing for fluid transfer
  • gaskets for medical equipment
  • seals for diagnostic and laboratory systems
  • profiles for cleanroom doors and panels

Platinum-cured silicone is particularly important in this sector due to its low extractables, biocompatibility and sterilisation resistance. Silicone withstands repeated autoclave, chemical and radiation sterilisation without losing mechanical properties.

For medical manufacturers, silicone provides confidence in material safety, consistency and regulatory compliance.

5. Automotive, EV Charging and Heavy Vehicles

Silicone in Aquaculture: A Durable, Non-Toxic Solution for Modern Fish Farming

Silicone in Aquaculture: A Durable, Non-Toxic Solution for Modern Fish Farming

Silicone materials are rapidly becoming a crucial part of aquaculture infrastructure and conservation— from cage coatings to sealing systems — with their unique characteristic features. With Jehbco Silicones’ proven expertise in high-quality silicone extrusions and components, the aquaculture industry stands to benefit from materials that improve sustainability, reduce maintenance costs, and enhance operational efficiency.

Advantages of using Silicone

Silicone rubber possesses a variety of properties that are well suited for harsh aquatic environments;

Chemical inertness & non-toxicity -Silicone is inert to water, making it safe for aquatic organisms when used in compatible application as it does not leach any harmful compounds.

Hydrophobic surface- Silicone repels water and minimizes adhesion forces for biological matter. Many biological organisms such as algae, bacteria, and biofilms require water to attach and grow, silicone surfaces make it harder for them to establish a strong bond due to its hydrophobic nature making it an advantage for aquaculture.

UV and weather resistance: long-term durability and minimal degradation, even after prolonged outdoor exposure makes it reliable than other elastomers.

Stability across temperatures — Maintains elasticity in both cold and warm environments, ideal for open-ocean or pond systems. Elasticity is maintained across extreme temperatures ranging from -50°C to 250°C.

Key Applications in Aquaculture

1) Anti-Biofouling surfaces

Silicone-coated netting decreases biofouling compared with raw nets and makes cleaning significantly easier. (Biofouling- the unwanted accumulation of organisms like algae, barnacles, and bacteria on nets and cages)

2) Cage & containment Seals

Resistance to saltwater corrosion, long-term watertight performance, and low maintenance requirements make silicone ideal for floating cages, ponds, and flow-through systems. Its flexibility in being tailored to desired shapes also makes it perfect for dependable seals.

3) Structural Components & Accessories

Silicone tubing, sleeves, and shapes are also valuable in:

Water handling systems — Flexible silicone tubing performs consistently in pumps, filters, and transfer lines due to its chemical inertness and non-toxic nature.

Sensor & instrumentation protection — Silicone’s weather resistance guards electrical and monitoring devices used in water quality testing.

Conclusion

Jehbco Silicones are the manufacturers of high-quality silicone extrusions and we are expertise in designing components for demanding environments.

Enhancing the oil resistance of silicone extrusions

Enhancing the oil resistance of silicone extrusions

When it comes to chemical resistance, silicone rubber is an exceptional material boasting strong chemical compatibility with a wide range of solvents and commonly used industrial reagents. This extraordinary chemical resistance stands out among other common elastomers, which often fail in contact with common solvents and oils. As silicone is naturally hydrophobic, it boasts excellent resistance to water and weathering, common alcohols, glycols and other medium polarity solvents. Additionally, silicone rubber has excellent chemical compatibility with common food oils such as vegetable oils or animal fat oils. This makes silicone particularly useful for a wide variety of food, water and medical grade applications.  

Typically, general use silicone also boasts good compatibility with and common industrial oils and lubricants, including mineral oil. However, extended exposure can lead to some swelling and decrease in hardness, which may be undesirable based on the end-use application of the silicone article, such as in gasket or other sealing applications. In these cases, specialized grades of silicone can be compounded and extruded which offer higher oil resistance than typical silicone grades.

At Jehbco, we specialize in custom silicone extrusions for a variety of high-spec applications. In addition to our standard general purpose and silicone grade materials, oil-resistant silicone can also be manufactured in 60 ShA hardness grades. This material has been tested for fluid resistance using standard ASTM reference oils IRM 901 and IRM 903, and also Glysantin® G40 aqueous coolant. For these grades, excellent retention of mechanical properties has been demonstrated, including test for hardness, tensile strength, elongation at break and volume change, thus providing our customers with peace of mind against product failure in applications where extensive oil contact is required.

Shock Vulcanization Strategies in Silicone Extrusion

Shock Vulcanization Strategies in Silicone Extrusion

In silicone extrusion, developing and maintaining products with custom geometries is a major challenge. Without any crosslinking, uncured, unprocessed silicone does not possess shape memory, which is imparted during the curing process. However, the total curing process can take several minutes, even at high temperatures >200 °C.[1] Thus, not only is shaping silicone difficult due to its tendency to expand after being shaped by the extrusion die, but maintaining its shape during the curing process is also a significant challenge. Moreover, this challenge is especially relevant for horizontal extrusion lines, where the profiles are subject to the influence of gravity, which can cause the desired geometry to sag or flatten if improperly processed.

To overcome this challenge, an often applied technique is shock vulcanization (also known as shock curing), in which the outer surface of the extrudate is rapidly exposed to high temperature, typically by passing it through a small chamber operating at extremely high temperatures (> 600 °C).[2, 3] This process cures the outside of the extrudate, firmly locking in the outer geometry, while the core continues to crosslink more gradually. Immediately stabilizing the surface through shock curing helps prevent collapse, sticking, or distortion in softer profiles, such as tubes or hollow sections, that might otherwise lose dimensional accuracy.[1]

By quickly setting the outer layer, shock curing allows the extrudate to be transported along conveyors or through ovens with minimal deformation, while the interior curing completes under controlled heating. The technique also enables higher line speeds and reduces handling issues in continuous production.

Although this process may seem simple, shock curing systems require careful control. Most notably, there is a fine balance between extrusion run-speed and operating temperature of the shock curing chamber. Excessive surface curing compared to the core can lead to internal stress and cracking. In extreme cases, the extrudate may exceed its autoignition temperature and spontaneously ignite, posing a severe safety hazard. Conversely insufficient shock curing leads to noticeable product deformation, rendering the final product unsuitable for use.

At Jehbco, we have over 50 years experience in extruding silicone in both basic and complex geometries, and utilizing shock curing systems to ensure your products are replicated with extremely precise tolerances on product geometries, without any formation of defects.

We operate an ISO 9001-certified Quality Management System, and our dimensional tolerances surpass standards specified under ISO 3302-1 (dimensional classes) and ISO 3302-2 (geometrical tolerances). Jehbco ISO 9001, ISO 3302-1 overview, ISO 3302-2 overview.

We’re proud to supply leading organisations including Mediquip and to provide tubing used in drinking water systems for Zip Water.

Why Medical Grade Silicone Tubing?

Proven biocompatibility

Medical grades are selected and tested for contact with human tissue and fluids, typically referencing ISO 10993 and/or USP Class VI biological evaluations, and – where relevant – FDA 21 CFR 177.2600 for elastomers in contact applications. Helpful primers: ISO 10993 vs. USP Class VI, and an overview including 21 CFR 177.2600 context: KEF America.

Wide working temperature range

Silicone maintains flexibility and key physical properties across a broad range (commonly -60 °C to +200 °C, with short-term higher peaks depending on grade), enabling both hot and cold processes and repeated sterilisation. Temperature references: Hanna Rubber technical sheet, Silclear note.

Chemical & taste/odour neutrality

Silicone’s inertness helps protect product integrity in pharma and biotech media transfer and potable-water flow paths. Background on medical rubber compounds and extractables: Apple Rubber medtech guide (PDF).

Sterilisation versatility

Compatible with steam/autoclave, ethylene oxide (EtO), and gamma/e-beam irradiation – a key advantage for reusable sets or validated single-use assemblies. Effects of sterilisation on silicone rubbers: Saint-Gobain study (PDF).

Key Applications of Medical & Food Grade Silicone Tubing

1) Peristaltic pumps (filling, dosing, media transfer)

Peristaltic pumps move fluid by compressing and releasing the tubing – the fluid never touches the pump mechanism, reducing contamination risk and simplifying cleaning validation. Silicone is ideal because it resists kinking, recovers after repeated compression (occlusion), and maintains stable flow over long duty cycles.n Principles and material stresses: Arrow explainer and Saint-Gobain on occlusion & spallation.

What to specify: inner diameter (ID) and wall thickness to hit target flow/pressure; pump-grade silicone for rebound and fatigue life; and validated sterilisation method (e.g., EtO vs. autoclave) per your device file.

This design minimises contamination and supports easy cleaning. Animation by Watson-Marlow Pumps Group: http://www.watson-marlow.com/

2) Surgical suction, anaesthesia & respiratory equipment

Silicone tubing tolerates repeated steam sterilisation and resists collapse under vacuum in operating-theatre suction lines and respiratory circuits. Process notes on sterilisation impacts: Saint-Gobain study (PDF).

3) Pharmaceutical & bioprocessing transfer

Smooth-bore silicone helps minimise hold-up and microbial niches in transfer lines, filtration skids and single-use assemblies. Common validated sterilisation routes for tubing include autoclave, EtO and irradiation (see DuPont Liveo note).

4) Diagnostics & laboratory automation

In analyser manifolds and reagent lines, silicone’s chemical compatibility and low extractables support stable baselines and repeatable results. Further background: Apple Rubber medtech guide (PDF).

5) Drinking water systems (Zip Water)

Silicone tubing is also used in point-of-use drinking water systems where purity, taste neutrality, and flexibility in compact spaces are critical. Jehbco provides tubing for drinking water systems for Zip Water. Silicone’s low taste/odour transfer and thermal resilience suit both ambient and heated dispensing paths (e.g., boiling/chilled mixer systems), and its clean extrusion surface finish supports hygienic design.

Silicone Extrusions

Silicone extrusions serve many industries, from food processing to aerospace. They are known for their versatility, durability, and reliability. In settings where other materials fail, silicone extrusions consistently perform, making them a reliable choice for challenging applications.   

Silicone extrusions are long, flexible shapes made from silicone rubber. They are made through a process called extrusion, where prepared silicone material is pushed through a specially designed die, which is an opening that shapes the final profile. This process creates continuous lengths with a consistent cross-section, whether it’s a solid cord, a hollow tube, or a custom gasket.  After extrusion, the silicone is cured through a process called vulcanization. This important step locks in the shape and improves its mechanical properties, such as flexibility, heat resistance, and tensile strength. 

How the Process Works at Jehbco 

  1. Material Preparation (Milling): 
    The process starts with preparing the raw silicone compound. At Jehbco, we add catalysts, curing agents, and pigments to meet specific customer needs. This milling process turns blocks of raw rubber into sheets of rubber with the necessary additives. Jehbco provide silicone in many colours and hardness levels, including hospital-grade and general-purpose options, allowing customers to choose the right fit for their application.   
  2. Extrusion: 
    The pre- prepared silicone is fed into an extruder, which is a machine that uses a rotating screw mechanism to push the material forward. As the silicone travels through the machine, it is forced through a precisely engineered die (There are two dies — one to craft the outer diameter and one to craft the inner diameter) creating the desired profile under closely monitored pressure and temperature. The result is a continuous, uniform extrusion, ready for curing. 
  3. Curing (Vulcanization): 
    The extruded profile then passes through a curing unit, typically a heated chamber or oven. This step cross-links the silicone molecules, setting the shape and enhancing strength, elasticity, and heat resistance. At Jehbco, the extruded rubber goes through a HAV (Hot Air Vulcanization) Belt, followed by additional curing in a high-temperature oven as needed. 
  4. Post-Processing & Quality Control: 
    Once cured from HAV belts, the extrusions pass through a cutting machine located at the end of the HAV belts, when required to cut the extruded profiles in to desired lengths. We conduct comprehensive quality checks at this stage — including profile verification, dimension measurement, surface inspection, bubble detection, and hardness testing to ensure every product meets strict quality standards. 
  5. Finishing & Packing: 
    Once the extruded parts are cooled, they are either packed as-is or joined and assembled to suit specific customer needs. Some of the hospital grade and general-purpose extrusions will undergo further vulcanization process in the dedicated ovens which will further enhance their stability. 

Types of Silicone Extrusions 

  • Solid Silicone Extrusions: 
    Dense and robust, ideal for applications requiring high strength and minimal compression. 
  • Sponge/Foam Silicone Extrusions: 
    Lightweight and compressible, perfect for cushioning, vibration dampening, and soft sealing. 
  • Platinum-Cured Silicone Extrusions: 
    Offer superior purity and mechanical performance, making them ideal for medical, pharmaceutical, and potable water applications. 

The field of silicone extrusion continues to evolve with cutting-edge innovations: 

  • Fluoro silicone Extrusions for enhanced chemical resistance 
  • Conductive Silicone for EMI/RFI shielding 
  • Reinforced Profiles for structural and high-strength applications 

As industries push for sustainable and high-performance materials, silicone extrusions are proving to be an essential component in modern engineering solutions.
