PURPOSE:To obtain a lubricating composition which has excellent abrasion resistance, does not injure the material in sliding contact therewith, and is useful as the material of bearings, etc., used at high temperature by incorporating a tetrafluoroethylene resin and a molten fluororesin into a polyphenylene sulfide resin. CONSTITUTION:5-40wt.% tetrafluoroethylene resin and 3-20wt.% melted fluororesin (e.g. a tetrafluoroethylene/perfluoroalkyl vinyl ether copolymer) are incorporated as the essential constituents into a polyphenylene sulfide resin to give a lubricating composition. A molding obtained from this composition has excellent abrasion resistance and does not injure the material in sliding contact therewith unlike a material having carbon fibers incorporated therein; therefore, it is suitable as the material of bearings, etc., used at high temperature by utilizing the heat resistance of the polyphenylene sulfide resin. |
