Fluorosilicone

Fluorosilicone
  • No Comments

Silicone is a very versatile elastomer that is used in numerous industries due to its superior physical and chemical properties, such as: excellent thermal resistance, higher longevity in hostile environment and flame retardancy [1]. These properties make silicone a desirable material for fuel systems, which unfortunately is not possible due to silicone’s limited fuel and oil resistance. However, this problem can be solved by substituting a small number of methyl groups in silicone (VMQ) with trifluorpropyl substituents, which results in fluorosilicone (FVMQ)[1].

The trifluoropropyl substituents enhance silicone’s chemical resistance to non-polar solvents, hydrocarbon fuels, oil, acids, and alkaline chemicals, making it a more ideal material for sealing in applications requiring resistance to hot fuels, oils and diesel based lubricants[2],[3]. This makes fluorosilicone a preferred material for static sealing and cushioning applications in aerospace, automotive and aviation industries [2].

 

Fluorosilicone is a Problem-Solving Material for Aviation Industry

Figure 1: Fluorosilicone is a Problem-Solving Material for Aviation Industry

 

Whilst it offers similar properties to silicone, there are several differences as shown in table below:

Unit Silicone[1] Fluorosilicone[4]
Hardness Range Shore A 3-90 30-85
Operating Temperature ℃ -50 to +250 -55 to +180
Tensile Strength N/mm2 5-12 8
Elongation at Break % 100-1,100 200%

 

As seen above, standard compound fluorosilicone has an operating temperature of up to 180℃. Due to this limitation, fluorosilicone is primarily used in fuel systems at temperatures up to 177℃[5]. However, there exists high-performance fluorosilicone that has a temperature range of -55℃ to 230℃[2]. It also has been reported that fluorosilicone could remain serviceable from -68℃ to 232℃, making it a fuel-resistant elastomer that is superior compared to fluorocarbon (FKM, such as Viton and Tecnoflon, poor low-temperature flexibility) and nitrile (NBR, heat resistance only up to 120℃)[2].

It is important to note that fluorosilicone is generally recommended for static applications only due to its relatively low tear strength, limited abrasion resistance and fair flex-cracking resistance [3],[5].

Fluorosilicone is usually used in the form of O-rings, gaskets, washers, diaphragms, and seals in fuel line connections, fuel control devices, electrical connectors, hydraulic line connectors, and fuel system access panels[6].

For more information and to keep updated with our research and development of fluorosilicone products, please do not hesitate to contact us.

Jehbco’s Silicone Products for the Rail Industry

Jehbco’s Silicone Products for the Rail Industry
  • No Comments

Rail is one of the most important modes of transportation in Australia. For passenger rail, in 2013 alone, about 2.3 million people travelled by train on a daily basis, totalling 850.3 million passenger trips [1]. On top of passenger rail, rail accounts for almost 50% of freight activity in Australia [1]. Additionally, Australia’s freight task is expected to grow by over 35% in the next 20 years, bringing the total volume to just over 1,000 billion tonne-kilometres[2]. Of this, rail is projected to grow to about 550 billion tonne-kilometres, about one-half of the total volume, maintaining its number 1 position in terms of volume [2].

Due to its sheer volume, it is pivotal for the rail industry to put performance and passenger welfare as their utmost priority. Hence, the rail industry has stringent aesthetic, technical and safety requirements for the materials and products that they use. Silicone meets these criteria due to its material advantages, such as [3]:

  • Cosmetically appealing (for more information please click here).
  • Non-toxic combustion products in the case of fire.
  • Compliance with fire safety standards such as UL 94, NFF 16101, BS 6853 and DIN 5510.
  • Can be exposed to wind, rain and UV rays for extended periods of time with almost no change in its physical properties.
  • Low compression set, resulting in increased long term reliability for anti-vibration, cushioning and sealing applications.

ISO 14001:2015 Environmental Management System
  • No Comments

Jehbco considers all the environmental issues related to its operations such as energy consumption, waste management, resource use and efficiency as important. Jehbco has a team which is currently working on implementing an Environmental Management System (EMS). Jehbco aims to get its EMS certified ISO 14001:2015 by the end of 2020.

ISO 14001 is a standard providing specific requirements for an effective environmental management system. The standard does not establish environmental performance requirements or telling organisations how to manage the environment. The standard provides a framework for an organisation to manage its activities, products and services in balance with its socio-economic needs1.

The standard is suitable for all types and sizes of organisation. The standard uses a high-level structure (see Figure 1) which is similar to the quality management system (ISO 9001:2015) that Jehbco has been holding for the last 20 years2. This means that ISO 14001 can be easily integrated into our existing quality management system.

 

Figure 1: High Level Structure

Figure 1: High Level Structure

The implementation of an environmental management system is going to bring many benefits to the organisation.  For example, the standard will help Jehbco to improve its resources efficiency by setting for example some environmental objectives. This implies that Jehbco will constantly look at reducing its general waste, raw material, water and energy use. This will have the key benefit to lower the business cost.

At Jehbco, we are always concerned with satisfying the expectations of our customers. Being ISO 14001 certified will ensure that our customers that we are meeting statutory and regulatory requirements. We will also encourage our suppliers to have a better environmental performance by integrating them into Jehbco quality and environmental management system.

ISO standards promote the application concept of the process approach. This means that the organisation manages the business as a system of processes linked together (i.e. network) and not by departments, people or products3. This helps the organisation to ensure that each process delivers its expected outputs as this could impact the inputs of what the other next processes need.

Additionally, the new revision of the standard introduced an emphasis on addressing the risks and opportunities of the organisation in order to achieve the intended outcomes of the environmental management system and prevent its undesired effects i.

Finally, like any ISO, the standard specifies the need for continuous improvement of the organisation system and approach to environmental concerns ii. The Plan Do Check Act model (see Figure 2) is an iterative four-stage approach process. The standard can itself be integrated into a PDCA model i.  The four stages are4:

  • Plan: identity, analyse, develop hypothesis and decide on one hypothesis to try first
  • Do: execute the plan
  • Check: see how it works
  • Act: review the results and make decisions to improve the process

 

Figure 2: Plan Do Check Act Model (PDCA)

Figure 2: Plan Do Check Act Model (PDCA)

 

While working towards implementing an environmental management system, people at Jehbco are also putting in place an occupational health and safety management system to obtain ISO 45001:2018 certification.

Silicone vs HNBR
  • No Comments

Whether it be designing a new product, or improving an existing piece of equipment, the choice of material is extremely important to ensure a low cost and smooth operation.

Silicone and Hydrogenated Nitrile (HNBR) have distinct physical and chemical properties, which determines what application each material is best suited for. Silicone and HNBR are both commonly used materials for o-rings, gaskets, seals, tubing and membranes. While both elastomers may be used to create similar products, the specific application and environment will ultimately determine whether HNBR or silicone will be the better choice for you. The table below summarises some of the key differences between the two materials.

 

HNBR Silicone
-30°C to 150°C -50°C to 230°C
Good compression set Excellent compression set
Good weather resistance Excellent weather resistance
Approx. tensile strength 20 MPa Approx. tensile strength 5 MPa
Great abrasion resistance Poor abrasion resistance
Not compatible with: esters, ethers, halogenated solvents, brake fluids, ketones Not compatible with: hydrocarbon fuels, alkalis and acids, steam over 121°C, trichloroethylene, aromatic hydrocarbons.
Compatible with: most oils and fuels, alkalis and acids, hot and cold water, alcohols. Compatible with: oils, brake fluids, hot and cold water, saltwater, high molecular weight chlorinated hydrocarbons, fire-resistant hydraulic fluid, ozone.

 

Both HNBR and silicone can operate at extremely low temperatures, although silicone is the far better option in high-temperature environments. Silicone can resist intermittent temperatures of up to 230°C, or up to 280°C if a heat stabiliser is added into the raw material.

HNBR has excellent tensile strength and good abrasion resistance, whereas silicone has good tensile strength, but poor abrasion resistance. For dynamic applications with friction, HNBR would most likely be a better option.  Granting this, silicone can be formulated to have improved tear strength, making it an ideal choice for applications such as vacuum sheeting and peristaltic pumps. Silicone also has the superior compression set, which makes it a better choice for applications requiring a long-lasting, reusable seal, especially in high-temperature environments.

While silicone has excellent resistance to ozone and UV, HNBR does not have the best resistance to ozone and UV, making silicone the more viable for most outdoor applications. However, HNBR is resistant to most forms of fuels and oils, whereas silicone is not compatible with a lot of hydrocarbon fuels. With this in mind, HNBR would be the superior choice for the automotive industry, although fluorosilicone compounds can be a good fuel-resistant alternative if a silicone-based material is required.

It is clear to see that there is merit in using either HNBR and silicone, depending on what physical properties you require and the operational environment. For help selecting a material for your application, consult our applications page and contact us with any questions.

Advantages of Silicone Products

Advantages of Silicone Products
  • No Comments

Jehbco Silicones manufactures extrusions which are made from 100% pure silicone elastomer and exhibits the characteristics of both inorganic and organic materials, which offers a number of advantages not found in other organic rubbers, such as [1][2];

a) Excellent resistance to heat and cold

Silicone rubbers have a broad operating temperature of -50°C to around +250°C for addition (e.g. platinum) cured and around +300°C for peroxide cured. Furthermore, it exhibits only slight changes in physical properties between -50°C to +180°C.

In terms of heat resistance, silicone rubbers can be used indefinitely at 150°C with virtually no change in its properties and can be used for 10,000 hours of more at 200°C.

Table 1 Operating life and temperature of silicone rubbers before any changes in properties.

 

Operating Temperature (°C) Operating life (hours)
150 Indefinite
200 10,000

 

Whereas in terms of cold resistance, the embrittlement point of silicone rubbers is -60° to -70°C, as opposed to typical organic rubbers which is between -20° and -30°C.

Table 2 Cold resistance comparison between organic rubbers and silicone rubbers.

 

Product Embrittlement Point (°C)
Organic rubbers -20 to -30
Silicone rubbers -60 to -70

b) Higher longevity in hostile environment.

On top of its excellent thermal resistance, silicone rubbers also have exceptional weatherability. It can be exposed to wind, rain and UV rays for extended periods of time with almost no change in its physical properties. Hence, it has higher longevity in hostile environment compared to organic rubbers. Furthermore, when phenyl groups are added to the polymer molecules, silicone rubbers are able to resist radiation and can be used in the manufacturing of cables and connectors used in nuclear power plants.

c) Good flame retardancy

Flame retardancy and/or self-extinguishing properties can be added to silicone rubbers by adding a small amount of flame retardant. When they do burn, unlike organic polymer rubbers, silicone rubbers do not produce black smoke or noxious gas. Hence, silicone rubbers are suitable to be used in consumer electronics and business equipment that are used in closed spaces such as aircraft and subways.

d) High purity

Silicone rubber is exceptionally pure compared to other elastomers. Furthermore, it is physiologically inert, which consequently affects living tissues to a lesser degree than by exposure to other organic polymers. Hence, it is suitable for use in the food and medical industry. Additionally, to ensure that our products are safe for sensitive applications, some of Jehbco’s products have certifications such as FDA CFR 21 177.2600 for food contact, AS/NZS 4020 for drinking water and USP Class VI for biological tests.

Due to its many advantages, silicone rubber is used in nearly every industry to improve the quality and function of various products and manufacturing processes.

Silicone vs Fluorocarbon
  • No Comments

When it comes to providing expert silicone solutions and rubber products, Jehbco Silicone is leading the way, growing its supply chain at a global scale. This article explores the properties of silicone rubber and how it compares to Fluorocarbon, an elastomer based on fluoro-rubber (FKM), also known as Viton (Fluoro Elastomer brand).

Although Silicone and Fluorocarbon are quiet similar in their properties, the fluorene (trifluoropropyl) groups do provide significant variances in chemical resistance and compatibility which develops a wider range of possible applications. The following table compares the key chemical and mechanical properties of Silicone and Fluorocarbon.

 

Fluorocarbon Silicone
-20° to 250° C -50° to 230° C
Excellent compression set Excellent compression set
Excellent weather resistance Excellent weather resistance
Approx. tensile strength 10 MPa Approx. tensile strength 5 MPa
Fair abrasion resistance Poor abrasion resistance
Not compatible with: amines, oxygenated solvents, lacquer solvents Not compatible with: hydrocarbon fuels, alkalis and acids, steam over 121 °C, trichloroethylene, aromatic hydrocarbons.
Compatible with: acids, alcohols, oxygenated solvents, alkali, fuels and hydrocarbons, mineral oils, Compatible with: oils, brake fluids, hot and cold water, salt water, high molecular weight chlorinated hydrocarbons, fire resistant hydraulic fluid, ozone.

 

Silicone and Fluorocarbon have very similar temperature ratings ranges, however Silicone is generally superior for low temperature applications at -20° C. Fluorocarbon is able to withstand higher temperatures at 250° C, although Silicone with the addition of heat stabiles and fame retardants, can exceed this and provide temperature ratings of up to 300° C making it an idea for high temperature applications.

They both share very similar abrasion resistance (fair- poor) which reduces their ability to perform well in dynamic applications and have similar ability to perform well in applications which demand durability due to their excellent compression and weather resistance. The tensile strength of Fluorocarbon is higher than Silicone at 10 MPa making it an ideal possible selection for high force and pressure applications.

In general, Fluorocarbon due to its chemical structure is an ideal material for applications that require strong chemical compatibly with hydrocarbons, oils and fuel/petroleum. As silicone is ideal for static high-temperature sealing applications, they have poor compatibility with oils and hydrocarbons which allow fluoro-elastomers such as fluorocarbon to be the best material choice.

Compliance with AS4020 Standard for products for use with drinking water
  • No Comments

Jehbco Silicones provides a wide range of tubing products:

  • Internal diameters can start from 0.5 mm
  • Outside diameters can go up to 60 mm
  • Different hardnesses (durometers) are available
  • Different colours are available

 

Figure 1: Different sizes of transparent silicone tubing

Figure 1: Different sizes of transparent silicone tubing

Jehbco’s tubing is primarily used for fluid transfer:

  • Water transfer for boiling and chilled appliances
  • Fluid transfer in medical application
  • Fluid transfer in batteries or engines specific to the automotive or energy industries
  • Fluid transfer in precision scientific equipment for science industry (ie. laboratories)

Our tubing for water and medical applications are made of platinum rubber. These products are thoroughly post cured to further decrease levels of extractables. The process is integral so our tubing is compliant with the AS/NZS 4020 standard. Jehbco has currently tested and complies with the AS/NZS 4020 standard for platinum 70 rubber for the following colours: transparent, red-transparent, blue-transparent and black transparent.

AS/NZS 4020 is a standard that is designed to test any products for use in contact with drinking water1. These products include tubing, pipes or any material used for applications in plumbing and water supply. The standard ensures that drinking water in contact with such products meet water quality values which are nationally recommended.

The standard provides methods of testing and compliance limits for the effect of a product/material2.  For the different tests of the standard, products are immersed in water or exposed to substances. Each test has specific procedures and are specific to the type of product2. The different methods of testing are described below2:

Taste of water: “A trained panel tastes water extracts to determine whether products release any compounds that impart discernible taste”ii

Appearance of water: Colour or turbidity of the water extract is measured.

Ability of a product to support the growth of aquatic micro-organisms: Dissolved oxygen levels are monitored during 8 weeks to examine the ability of the product to support bacterial growth.

Cytotoxic activity of water extract: Water extract is placed in contact with mammalian cell lines. Any adverse effect on the cell health is considered as evidence of a cytotoxic effect.

Mutagenic activity of water extract: An AMES test is used. Specific bacteria are mixed with the water extract. Any change in the bacteria’s genetic nature is considered as evidence of mutagenic activity

Extraction of metals: Levels of arsenic, antimony, barium, cadmium, chromium, copper, lead, mercury, molybdenum, nickel, selenium and silver in the water extract are analysed and compared to the limits of the National Health and Medical Research Council (NHMRC) guidelines.

High-Temperature tests: Products in contact with hot water are tested at high temperaturesii.

Products are required to comply with all the tests relevant for that product type to be certified by AS/NZS 4020 standard. Jehbco’s tubing is regularly tested as the test reports for the AS/NZS 4020 test are valid for 5 years3.

To learn more about our silicone tubing, see our tubing page or contact us.

Seals, Gaskets and Compression set

Seals, Gaskets and Compression set
  • No Comments

From food processing to petrochemicals,  silicone seals and gaskets find a multitude of applications. The key factor in understanding what makes silicone preferable over other materials is its Compression Set Resistance.

Compression set resistance is the ability of rubber to return to its original thickness after prolonged compressive stresses at a given temperature and deflection1.

Compression set results for a material are expressed as a percentage of the maximum figure. A compression set of 100% says that the elastomer never recovers from its compressed state. The lower the percentage figure, the better the material resists permanent deformation under a given deflection and temperature range. A low value means that the tested rubber has a good capacity to keep its sealing properties and will have a better chance of effecting a seal in a given working environment for a longer period2.

The sealing application could be either static or dynamic with combinations of contact-types i.e. non-metal to metal, or metal to metal. To ensure the right seal, the shape of the seal must be retained over the time period it is designed for in every case3. The property that directly corresponds to shape retention is compression set. We help our customers identify the right silicone with the right compression set for their application.

You can find the compression set values in our Certificate of Conformance, which we provide on request.

 

An example of the technical specification we provide as part of the Certificate of conformance.

After the rubber selection, choosing the correct extrusion profile is the next step in the design process. Customers can provide their own extrusion designs and samples or provide us with the details of the application for us to create a new design from scratch.

Jehbco specialises in manufacturing gaskets and o-rings. Ultimately, it is the manufacture of gaskets to the right dimension and strength that makes the seal work and fulfil its purpose. Our gasket manufacturing quality assurance comprises comprehensive steps right from generating drawings with dimensional tolerances to sequential step by step inspection of cut lengths, cut quality, jig preparation and joint strength.

The testing phase usually involves us sending samples and the customer testing them at their facility. We also have in-house testing facilities to check the joint strength and coefficient of friction. We have a dedicated O-ring test rig on which we could carry-out leak tests and compression tests.  We can develop O-rings made of silicone rubber and sponge to match our customer’s requirement based on their sealing data. Please refer to our O-ring design article here.

To match our products with your application, please see our applications page and contact us if you have any silicone queries.

Silicone Colour Matching

Silicone Colour Matching
  • No Comments

Jehbco Silicones provides silicone solutions to a wide variety of industries, ranging from construction, to food and beverages. For many projects, our customers are happy with a standard colour such as white, but we understand that some projects have strict aesthetic requirements, and as such require a little more attention.

 

Description: A small sample of the colours we can produce at Jehbco Manufacturing

Description: A small sample of the colours we can produce at Jehbco Manufacturing

 

For example, blue is the standard colour for seals in the food and beverage industry, as the high contrast of colours can alert production staff if the seal is damaged and contaminates the food product. Our silicone seals are perfect for this application as not only are we able to make practically any of our existing or new profiles in blue, but they are also 100% food-grade.

Another example of where we would use our custom colour matching services would be for the architectural industry. We know that any design-focused industry such as architecture places a strong emphasis on the aesthetics of the final project. As such, we always work with our customers to develop the perfect custom solution in terms of design and appearance. Whether it be matching the colour of our silicone expansion joints to your panelling, or implementing the perfect colour combination using our window glazing seals, Jehbco will be able to deliver.

Beyond the more obvious examples above, some of our customers purchase a wide range of products from us and colour code each individual item to help differentiate similar products, or to prevent confusion when receipting in goods. One customer of ours purchases a range of different sized silicone tubes, and requests that every different sized tube is a different colour. In the past, our customer told us that the wrong sized tubing would often be installed by their production team due to the different sizes being so hard to tell apart. After switching over to our custom-coloured tubing, the number of defects due to incorrect tubing sizes almost dropped down to zero!

It is clear to see the benefits of using Jehbco’s custom colour matching services, the possibilities are only limited by your imagination. At Jehbco, we only produce 100% pure silicone products for your guaranteed peace of mind. If you have an idea that might require a custom colour, or want to manufacture a custom solution that you can be confident with, feel free to consult our applications page and contact us with any questions.
