Product Description
FFKM FFPM(Perfluoroelastomer)
Perfluorelastomers (FFKM) have a fully fluorinated polymer backbone resulting in fluorine content of over 71%.
As all of the bonds on the backbone are carbon-fluorine then FFKM materials offer the ultimate thermo-chemical resistance shown by the good long-term high temperature compression-set resistance.
As all of the bonds on the backbone are carbon-fluorine then FFKM materials offer the ultimate thermo-chemical resistance shown by the good long-term high temperature compression-set resistance.
Although all FFKM polymer backbones are fully fluorinated the cross linking systems used to join the polymer chains together differ significantly, resulting in differing temperature and chemical resistance.
Specification
FF500B has excellent heat resistance, extensive medium resistance, low compression set and strong seal retention at extreme temperatures. It is copolymerized by tetrafluoroethylene monomer(C₂F₄), perfluoromethyl vinyl ether monomer(PMVE) and crosslinked monomer. The monomer at vulcanization point contains cyano group, which can be vulcanized with BOAP triazine.
FF600AT is a chemical resistant perfluoro elastomer, and it can be vulcanized with peroxide. It has a wide range of corrosion-resistant medium sealing ability and excellent compression set value. FF600AT has better high temperature resistance than Type A FFKM rubber, and its long term use temperature reaches 290℃.
