Chemical Resistant Rubber

The unique cross-linking system employed in perfluoroelastomers makes them the most chemical resistant rubber available. The molecular structure of Perlast® perfluoroelastomers is very similar to PTFE providing excellent thermal stability and chemical resistance against virtually all chemicals.

Perlast® G80A offers the broadest chemical resistance of all perfluoroelastomers, being able to withstand acids, bases, solvents, amines, ethers, steam and oils, with the ability to operate up to a maximum temperature of 260°C (500°F).

In a standard immersion test Perlast® G80A shows little volume swell even after 1000 hours @ 250°C (482°F).

FKM sample swells excessively and even the competitive FFKM sample shows unacceptable swelling.
