Perfluoroelastomer (FFKM, Kalrez®, Chemraz®, Perlast®)

Accurate Definitions: Perfluoroelastomers are a class of synthetic rubber materials characterized by their high resistance to heat, chemicals, and compression. They are derived from the polymerization of perfluorinated monomers, which give them exceptional stability and durability in extreme environments. Perfluoroelastomers are commonly referred to by their industry designations such as FFKM, or by brand names like Kalrez®, Chemraz®, and Perlast®. These materials maintain their elasticity and sealing performance across a broad temperature range, making them ideal for use in critical applications where other elastomers would fail.
