subject: High Temperature Sealing For Maximum Sealing Performance [print this page] Sealing is one of the most common processes employed in various industries. Recent technological innovations have enabled companies to achieve maximum sealing performance during various processes. High temperature sealing process is one of such processes that changed the entire sealing process significantly. It is known that if a seal is kept on high temperature for a longer period of time the elastomers result in steady deterioration. It also results in the change in the compression, set and volume. The hardness of the elastomers amends in two stages. In the first stage, the seal gets softer. It leads to the flow of elastomer through the clearance gap. Further, if the seal get too hot, the derived chemical reactions will start with the elastomer and it will become harder.
There are various factors that determine the stability and performance of the seal. Out of such properties, the selection of right material for sealing is of utmost importance. The revolutionary elastomers and high performance elastomers have enabled companies to achieve high performance and durable sealing solutions. The high temperature sealing technique gives high temperature stability and outstanding chemical resistance. It also supports outstanding mechanical properties. Moreover, these high performance elastomers are FDA, USP Class VI and 3A compliance.
The high temperature sealing solutions are like a much desired things the companies looking for which enable them to develop sealing solutions that not only provides high stability in high temperatures but durable too. These high efficient perfluoroelastomers have been especially manufactured for high temperature sealing and are capable enough of performing at temperatures up to 325C (617F) and 320C (608F) respectively, whilst maintaining excellent chemical resistance.
These elastomers have excellent mechanical properties that set them apart from ordinary high temperature perfluoroelastomers. Their low compression set properties depicts that they are solid enough to retain their chemical resistance in spite of being mechanically wearied.
Perlast Ltd is a leading manufacturer of specialist perfluoroelastomer parts for high temperature sealing process for demanding applications in the food, pharmaceutical, semiconductor and chemical processing industries.
