Perlast® Perfluoroelastomer FFKM
PPE manufactures and supplies the Perlast® range of high performance perfluoroelastomer materials (FFKM).
Perfluoroelastomer (FFKM) is the most chemically resistant elastomer available and is effectively a rubber form of PTFE. Perlast® perfluoroelastomer grades provide other properties which prove most valuable in critical sealing applications where purity, high temperatures and retention of sealing force are paramount.
The Perlast® range of perfluoroelastomer materials are at the leading edge of polymer technology. They have been developed to offer superior sealing solutions with enhanced performance and improved functionality, which is proven in the field (see case studies).
Features of Perlast® FFKM seals include:
High temperature stability up to 327°C (620°F)
Almost universal chemical resistance
Outstanding mechanical properties
High purity materials
FDA, USP Class VI and 3A compliance
Highest quality parts
Perlast® is a registered trademark of Precision Polymer Engineering Ltd The ultimate perfluoroelastomers for sealing applications where chemical resistance and high temperature performance are critical.
