The recent advancements in sealing technology have enabled the industries to incorporate the use of perfluoroelastomers and other high performance elastomers to generate high efficient sealing systems for enhanced functionality and utmost performance. If a seal in put on high temperature for a longer period of time, the elastomers will depreciate gradually. It results in the change in the compression, set and volume. The hardness of the elastomer changes in two stages. Firstly, the seal will become softer. It results in the flow of elastomer through the clearance gap. Second, high temperature seal promotes chemical reaction which in turn into hard elastomers.
The selection of right material is of prime importance in order to make the seal heat and chemical resistant. The latest perfluoroelastomers and high performance elastomers offer unmatched temperature sealing. These seals also provide high temperature stability and excellent chemical resistance. These high performance elastomers are FDA, USP Class VI, and 3A compliance.
The latest perfluoroelastomers seals are specifically developed for high temperature sealing and manufactured to work at temperatures up to 325°C (617°F) and 320°C (608°F) respectively, whilst maintaining excellent chemical resistance. These high performance elastomers support outstanding mechanical properties which set them apart from ordinary high temperature perfluoroelastomers
