FEPM O-rings

FEPM O-ring, also called AFLAS O-ring, is a kind of sealing ring that can be used at high temperature of 200℃ for a long time, and the FEPM material has excellent water vapor resistance. FEPM is more resistant to chemical acid and alkali than ordinary fluorine rubber.

Application of FEPM O-rings and moldings

FEPM is a member of a new generation of fluoroelastomers compounded especially to provide unique properties for specific applications. The primary uses for Aflas are in parts for oil drilling equipment. Aflas can be crosslinked (cured) using a variety of systems, but generally peroxides are used to provide the best all around environmental resistance.
