FFKM Raw Rubber
FFKM-N is a high temperature perfluoroelastomer (FFKM) which is a copolymer of tetrafluoroethylene and perfluoromethylvinylether (TFE+PMVE+ CSM). FFKM-N based rubbers demonstrate excellent chemical resistance in a wide range of aggressive substances including inorganic and organic acids, alkalies, most of polar solvents, amines. FFKM-N operating temperature range is from -10° to 315°C. The product is processed by compression molding.
