Abstract
A rubber composition having low friction is proposed which contains a thermoplastic fluororesin, a thermosetting fluororubber and a low-molecular weight fluorine-containing polymer.
Claims4
A rubber composition comprising at least one thermoplastic fluororesin as a first ingredient selected from the group consisting of a tetrafluoroethylene-ethylene copolymer, a tetrafluoroethylene-perfluoroalkyl vinylether copolymer and a tetrafluoroethylene-hexafluoropropylene copolymer, a thermoset fluororubber as a second ingredient, and a tetrafluoroethylene polymer as a third ingredient represented by formula ##STR6##
A rubber composition as, wherein said thermoset fluororubber as the second ingredient is at least one polymer selected from the group consisting of a tetrafluoroethylenepropylene copolymer, a vinyldidene fluoride-hexafluoropropylene copolymer, and a vinylidene fluoride-hexafluoropropylene-tetrafluoroethylene copolymer.
