High Temperature Sealing Solutions for Enhanced Performance

High Temperature Sealing Solutions for Enhanced Performance

Sealing is required for various industrial purposes and in order to get maximum sealing performance there is a need to incorporate new technology. Recent innovations in technology have enabled industries to achieve high efficient and durable sealing solutions. The latest high temperature sealing is essential to achieve optimum performance and enhanced functionality. If a seal is put on high temperature for a longer period of time the elastomers result in gradual deterioration. It also leads to change in the compression, set and volume. The hardness of the elastomers changes in two stages. In the first stage, the seal becomes softer. It leads to the flow of elastomer through the clearance gap. Second, if the seal becomes too hot, the resultant chemical reactions will initiate with the elastomer and then it will become harder.

There are various properties responsible for the stability and performance of the seal. Among these properties the selection of right material for sealing is pretty much important. The latest induction of elastomers and high performance elastomers has enabled companies to get high performance and durable sealing solutions. This high temperature sealing technique results in high temperature stability and excellent chemical resistance. It also assists outstanding mechanical properties. These high performance elastomers are FDA, USP Class VI and 3A compliance.

This high temperature sealing solution acts as a boon to various industries that were looking for increase life time performance seals and enhanced sealing performance. There are various other advantages associated with high temperature sealing such as enhanced machine/equipment output, decreased machine/equipment downtime, improved process conditions, reduced process contamination, and lower cost of ownership.

These high efficient perfluoroelastomers have been especially developed 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 pose outstanding mechanical properties that set them apart from ordinary high temperature perfluoroelastomers. Their low compression set properties indicate that they are capable of retaining their chemical resistance in spite of being mechanically frazzled. It leads to reduction in the effectiveness of stree-induced chemical attack and thus extended seal life in high temperature sealing applications.

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.
