摘要： A polyacetal resin composition comprising a polyacetal, a polyolefin, and carbon black dispersed in a special morphology, which is excellent in thermal conductivity, sliding property, moldability, and molding appearance. The composition provides a sliding part for electrical equipments, e.g., gears, bearings, cams, etc., which has excellent sliding properties, makes low noise, and exhitits high abrasion resistance.
