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 a melt flow rate (230.degree. C. under a load of 2.16 kg) 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 derived from an aromatic vinyl in an amount of 22% by weight or less and has a melt flow rate (230.degree. C. under a load of 2.16 kg) of at least 5 g/10 min,0 to 16% by weight of a hydrogenated block copolymer (C) 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 derived from an aromatic vinyl in an amount of at least 25% by weight and has a melt flow rate (230.degree. C. under a load of 2.16 kg) of 10 g/10 min or less,1 to 10% by weight of an aromatic hydrocarbon copolymer (D),0 to 10% by weight of a crystalline polyethylene (E),0 to 10% by weight of a soft ethylene/.alpha.-olefin copolymer (F), and5 to 25% by weight of an inorganic filler (G) having an average particle size of 0.1 to 3 .mu.m.
