Is Jehbco’s 10″ Silicone Sleeve Ideal for Corona Treatment?
In order to achieve effective printing on plastic substrates, corona surface treatment is essential. The printing industry continues to seek for reliability and flexibility with corona treatment. Applications that don’t frequently change and without down-time but offer the handling and financial benefits of the sleeves are important factors being considered.
With treating corona the goal is to elevate the material’s surface energy providing its adhesion and wettability. However, the system not properly run and maintained is ineffective in treating a substrate.
There are series of problems that can happen when a system for corona treatment conveys too much or too little energy to a substrate. Problems started to occur after a usage of excessive amounts of ink aiming to cover up an inadequate treatment level resulted from an attempt to achieve satisfactory printing results using undertreated materials. Overtreatment can also result to ruining the material itself and to having blockage issues at the same time.
Whereas low dyne levels, poor adhesion and inadequate wettability can at the same time happen. Whilst the increasing demands of U.V. and water-based inks, concurrence with polyethylene and polypropylene are causing corona treating a critical part of the converting process. Failure in corona treatment will cost so much time and money that can eventually jeopardize a printing business. Some troubleshooting information, preemptive measures and correct choice of material are important for corona treaters.
The material type, suppliers and thickness are all significant which can affect the appropriate power level. Prior to addressing corona treater issue, it is essential to consider vital parameters in choosing the material to use as corona sleeves such as dielectric constant and strength, ozone resistance, cut resistance, heat dissipation, porosity, ease of field repair, maximum service temperature, hardness and cost.
Here at Jehbco, our silicone sleeve manufactured from silicone rubber compound provides outstanding electrical, chemical and thermal resistance, making it ideal on harsh environment like during the corona treatment process. Jehbco silicone sleeves are manufactured specifically as electrical dielectric sleeves, and are produced with extreme maximum tolerance, seeing to it reliability and consistency in its performance.
Jehbco silicone sleeve do not crack or break under weird web tension; need much lower web tension; sleeve treat are functional with much smaller air gap; easy to replace; having good electrical insulation; withstand ozone corona discharge; ideal for continuous operation at high temperature without loss of any dielectric and mechanical properties; with high dielectric strength; resilience and flexibility on insulation case on to treatment roll and long life.
Consequently, our silicone sleeve for corona treaters are excellent material to use, since ours at Jehbco are chemically stable with excellent dielectric properties and chemical resistance, formulated for maximum resistance to ozone and corona discharge. Jehbco corona sleeving has been extruded perfectly elliptical. This ensures longevity and smoothness in application with no unnecessary “bumps” during operation.
