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.
