Description
FEPM/AFLAS is a high-performance fluoroelastomer with excellent resistance to amines, strong bases, high-temperature steam, acids, fuels, and various chemicals. Compared to conventional FKM, FEPM offers greater stability in alkaline environments and high-temperature steam without undergoing dehydrofluorination reactions. WINBEST offers custom peroxide curing systems to meet more demanding media requirements.
Applications
Oil & gas extraction equipment (resistant to amines, H2S)·
High-temperature steam valve seals
Chemical processing equipment O-rings
Caustic pump seals
Power plant steam system gaskets
Automotive engine valve train seals
