Mechanical frazzling of seal are no more the problems because the latest technology and development proved to be a boon to industries like semiconductor, chemical processing, food and pharmaceutical etc. the latest technology has introduced the usage of perfluoroelastomer and other high performance elastomers for excellent high temperature sealing which delivers high performance and super enhanced functionality.
What really matters is the selection of right materials and it of greater importance if the seal has to made both heat resistant and chemical resistant. Perfluoroelastomers and high performance elastomers provides enhanced efficiency for high temperature seal. These high temperature seals offer high temperature stability and outstanding chemical resistance. FDA, USP CLASS VI AND 3A are the high performance elastomers. These elastomers contain superior mechanical properties that make them distinct from other seals.
The other benefits of high temperature sealing is enhanced machine and equipment output, reduced machine downtime, optimized process conditions, reduced process contamination, and reduced cost of ownership. Elastomers deteriorate gradually when a seal is kept at high temperature for a longer period of time; it results in the change of compression, set and volume. Elastomer’s hardness changes in two phases. The seal becomes softer and results in the flow of Elastomer through the clearance gap and high temperature of seal results in the subsequent chemical change and seal becomes harder.
