FFKM/FFPM has excellent resistance to high temperature hardening performance, but also both the flexibility of rubber and  corrosion resistance. In the -20F-615F range, perfluoroether o-ring (seal), pull length and sealing are very good. Perfluoroether o-rings (seals) can withstand the corrosion of most chemicals, including organic acids, inorganic acids, alkalis, ketones, alcohols, aldehydes and fuels. Therefore, the perfluoro o-ring (seal) can be long-term service in most chemical processes. In the other rubber products will expand or failure of the medium o-ring (seal) still maintain the original quality. Easy to install, better than the metal seal to adapt to the incorrect installation, will not cause wear and tear.
FFKM/FFPM characteristics
Features of perfluorinated rubber
First, high temperature;
Second, strong resistance to corrosion;
Third, ultra cleanliness
Application areas
First, the chemical process and oil refining: The sealing products for mechanical seals, pumps, reactors, mixers, compressor housings, valves, all kinds of instruments and other equipment. Usually used as a seat, stem packing, diaphragm and gasket.
Second, the analysis and process instruments: partitions, diaphragms, cylindrical accessories, hoops, gaskets and so on.
Third, semiconductor manufacturing
Four, food and medicine
