Tetrafluoroethylene rubber compound
Fluoroelastomer is a copolymer of tetrafluoroethylene and propylene. Fluoroelastomer has unique properties compared to traditional FKM-type fluoroelastomers and is suitable for demanding applications such as oil and gas, chemical processes, wires and cables, industrial equipment, food processing, pharmaceuticals, heavy diesel and automotive industries. Fluoroelastomer has excellent weather resistance, heat resistance, acid and alkali resistance, various solvents, ozone and water vapor, especially alkali resistance, which is much better than traditional FKM-type fluoroelastomers. It is classified as FEPM according to ASTM D 1418. and its Chinese name is tetrafluoroethylene rubber.
