Perlast®
Perlast® Perfluoroelastomer is a special type of rubber material designed to offer the unique chemical resistance of PTFE. It shares with PTFE a polymer backbone consisting of carbon atoms protected by fluorine atoms, making it very inert to chemical attack. As a rubber, therefore, it is resilient, so it doesn't creep or flow but retains sealing force over a long period. Perlast can be used in long-term conditions and has a very low oxygen permeability. It also stretches - aiding installation. For additional information on Perlast, we recommend the White Seal website.
