Compounds - Aflas (FEPM)

Aflas

AflasExcellent resistance to a wide variety of aggressive chemicals. Aflas is known for its use in oil field applications and its electrical resistance properties. This elastomer is a copolymer of tetrafluoroethylene (TFE) and propylene. Its chemical resistance is excellent across a wide range of aggressive media.

Both o-rings and gaskets can be made from Aflas materials.
