Abstract
A polypropylene resin composition for use in automotive inner and outer trims, comprising 50 to 85% by weight of a crystalline polypropylene (A) having an MFR (230° C.) of 7 to 70 g/10 min, 2 to 16% by weight of a hydrogenated block copolymer (B) obtained by hydrogenating at a hydrogenation ratio of at least 90% an aromatic vinyl/conjugated diene block copolymer which contains an aromatic vinyl block polymer unit in an amount of 22% by weight or less and has an MFR (230° C.) of at least 5 g/10 min, and 5 to 25% by weight of an inorganic filler (G) having an average particle size of 0.1 to 3 &mgr;m as essential components. This composition may contain, as optional components, another hydrogenated block copolymer (C), an aromatic hydrocarbon copolymer (D), a crystalline polyethylene (E) and a soft ethylene/&agr;-olefin copolymer (F). This composition is excellent in heat resistance, rigidity and impact resistance and can provide a molding having beautiful appearance.
