PURPOSE:To obtain a composition of significantly improved moldability while retaining the excellent characteristics inherent in fluororesin, also causing no corrosion of the molding machine, by kneading, under a molten state, a fluororesin of specific particle size and polyolefin resin. CONSTITUTION:The objective composition can be obtained by kneading, under a molten state, (A) 90-60wt% of a fluororesin of an average particle size 2-20mu and (B) 10-40wt% of a polyolefin resin, alternatively, another composition comprising (1) 85-50wt% of said fluororesin, (2) 5-10wt% of graphite or molybdenum disulfide, (3) 10-40wt% of said polyolefin resin will have higher resistance to wear. Said fluororesin should be polytetrafluoroethylene, whereas the polyolefin resin either polyethylene or polypropylene one. |
