SLIDING PARTS MADE OF POLYACETAL RESIN

摘要

A sliding part improved in sliding characteristics while retaining excellent mechanical properties and moldability inherent in polyacetal resin. Namely, a sliding part made of a composition comprising (A) 100 parts by weight of a polyacetal resin, (B) 0.05 to 20 parts by weight of a lubricating oil taking the form of a liquid at 200°C, and (C) 1 to 20 parts by weight of a core-shell polymer having both a core made of a rubbery polymer and a shell made of a glassy polymer consisting of a vinyl copolymer having oxygen-containing polar groups is reduced in the contact area in sliding by virtue of its being a molded article having a matte surface, thus exhibiting excellent sliding characteristics.
