FFKM
Perfluoroelastomer (FFKM)
Perfluoroelastomers (FFKM) feature fully fluorinated polymer chains, providing exceptional performance in terms of heat and chemical resistance. They exhibit excellent resistance to fuels, various lubricating oils and greases, mineral-based and hydraulic fluids, solvents, alcohols, as well as most acids and alkalis.
Cure System
Peroxide-cured vs. Nitrile-cured
Standard FFKM compounds are typically cured using peroxide.
FFKM compounds cured with nitrile offer superior heat resistance compared to those cured with peroxide.
Other Common Variations
FFKM exhibits outstanding resistance to high temperatures, oils, solvents, flames, chemicals, and weathering. It finds applications in semiconductor manufacturing, chemical processing, aerospace, and various industrial settings. Additionally, FFKM is suitable for use in the oil and gas industry, where it withstands highly aggressive media, high pressures, and extreme temperatures. It also shows resistance to rapid gas decompression.
