Polyacetal resin composition, method for producing the same, and molded article

摘要

A polyacetal resin composition and molded article having a high metallic gloss, small change in a color tone according to the viewing angle, high weld performance, and high mechanical properties can be provided in which the amount of formaldehyde to be produced in molding and recycle is suppressed, the mold deposit is improved, and the repeated impact resistance after aging is high. A polyacetal resin composition comprising: (A) 100 parts by mass of a polyacetal copolymer resin, and (B) 0.1 to 10 parts by mass of an aluminum pigment, the aluminum pigment having a coin-like or flake-like flat shape, a volume average particle size D50 of 15 to 50 μm, an average surface roughness Ra of 20 to 50 nm, and an average height Rc of depressions and projections in a surface roughness curve of 80 to 200 nm.
