PURPOSE:To obtain a molded article having low kinetic friction coefficient and high critical PV value, and suitable as a sliding part, by mixing a polyacetal resin with silicone oil, and molding the resultant powder, granules of flake e.g. by compression molding. CONSTITUTION:100pts.wt. of a polyacetal resin is mixed with 0.01-6wt% silicone oil, and the obtained powder, granule or flake is molded by compression molding, injection molding or extrusion molding to obtain a moled article. The silicone oil is the one having a kinetic viscosity of 5-10<6>cst, preferably 5-10<3>- 10<5>cst at 25 deg.C. |
