Tetra-Fluoroethylene/Propylene – FEPM

Another fluorinated elastomer, this also has high temperature resistance up to 450°F/232°C and similar hydrocarbon fluid resistance to that of a FKM but with poorer compression set. It has good resistance amines and steam and is commonly found being used in the oil patch industry.

Excellent resistance to Amines
Excellent resistance to Steam up to 450°F/232°C
Excellent chemical resistance
Wide temperature range from 20°F to +450°F
