FFKM
Perfluoroelastomers (FFKM)
Perfluoroelastomers(FFKM) contain fully fluorinated polymer chains and hence offer the ultimate performance of elastomers when considering heat and chemical resistance. Excellent resistance to fuels, all types of lubricating oils and greases, mineral-based and hydraulic fluids,solvents, alcohols, most acids and alkalis.
Cure system
Peroxide-cured vs. Nitrile-cured
Standard FFKM are usually peroxide-cured. FFKM compounds with nitrile-cured have better heat resistance than the peroxide cured.
Other Common Variations
- FFKM has excellent resistance to high temperature, oil, solvent, flame,chemical and weather, and it is usually applied in semiconductor, chemical processing, aerospace and many industrials.
- FFKM can also be used in the oil and gas industry with highly aggressive media, high pressure, and in extreme temperature. They are resistant against rapid gas decompression as well.
