Abstract: Lead-free solid lubricant to be embedded in pores or grooves formed at a sliding surface of a sliding member body, comprising 20 to 40% by weight of at least one wax selected from hydrocarbon waxes, higher-fatty acids, esters of higher-fatty acid and amides of higher-fatty acid, 20 to 40% by weight of melamine cyanurate, and 20 to 50% by weight of a polytetrafluoroethylene resin. The lubricant exhibits sliding properties identical to or higher than those of lead-containing solid lubricants, even under high load conditions.

Abstract: There is provided a lead-free solid lubricant exhibiting sliding properties identical to or higher than those of lead-containing solid lubricants, even under high load conditions. A solid lubricant for being embedded in pores or grooves formed at a surface of a sliding member body, comprises: 20% to 40% by weight of at least one wax selected from the group consisting of hydrocarbon waxes, higher-fatty acids, esters of higher-fatty acid and amides of higher-fatty acid, 20 to 40% by weight of melamine cyanurate, and 20 to 50% by weight of a polytetrafluoroethylene resin.

Abstract: The disclosure describes a polyacetal resin composition comprising 100 parts by weight of a polyacetal resin (A), 0.3 to 10 parts by weight of an olefin copolymer (B) composed of 30 to 70 wt % of ethylene-propylene-diene rubber (B.sub.1), 30 to 70 wt % of an ethylene-vinyl acetate copolymer (B.sub.2) with a vinyl acetate content of 18 to 40 wt % and 1 to 25 wt % of an ethylene-(C.sub.4-6)olefin-1 copolymer (B.sub.3), and 0.1 to 10 parts by weight of a styrene-based thermoplastic elastomer (C) having a functional group.

Abstract: Disclosed herein are a fluororesin composition for a sliding member comprising a fluororesin, at least one of fillers selected from the group consisting of glass fiber, glass powder, carbon fiber and carbon powder, and a phosphate, and a sliding member thereof.
