Perfluoroelastomers (FFKM)

Perfluoroelastomers (FFKM)

Category O-Rings and Elastomers

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

Cure system – Peroxide-cured vs. Nitrile-cured
Standard FFKM is 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 semiconductors, 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 temperatures. They are resistant against rapid gas decompression as well.
