Abstract
An object of the invention is to provide a resin composition, from which a molded article having high durability, sliding property and wear resistance can be produced with a high productivity. The present invention provides a polyacetal resin composition containing 100 parts by mass of a polyacetal resin (A) and 10 parts by mass or more and 100 parts by mass or less of a glass filler (B), in which when a molded article formed of the polyacetal resin composition by molding is fractured by application of tensile force, the surface of the glass filler (B) protruding from a fractured surface of a fractured molded article is covered with a component containing the polyacetal resin (A) having an average thickness of 0.2 μm or more and 3.0 μm or less.
Claims6
A molded article formed from a polyacetal resin composition containing 100 parts by mass of a polyacetal resin (A) and 10 parts by mass or more and 100 parts by mass or less of a glass filler (B) wherein, at least one acid is contained as a material having a function of modifying the surface of the glass filler (B) and wherein, when the molded article is fractured by application of tensile force, the surface of the glass filler (B) protruding from a fractured surface of a fractured molded article is covered with a component comprising the polyacetal resin (A) having an average thickness of 0.7 μm or more and 3.0 μm or less,
- wherein the polyacetal resin (A) contains a block component including a hydrogenated polybutadiene component.
