Patent ID: 8686088

Claim:
A polypropylene resin composition comprising: 100 parts by weight of a resin composition (F) comprising: 50 to 75% by weight of a polypropylene (A) having a melt flow rate (ASTM D1238, 230Â° C., 2.16 kg load) of 20 to 300 g/10 min; 5 to 15% by weight of an ethylene-Î±-olefin copolymer or an ethylene-Î±-olefin-diene copolymer (B-1) having a melt flow rate (ASTM D1238, 230Â° C., 2.16 kg load) of less than 0.4 g/10 min; 5 to 15% by weight of an ethylene-Î±-olefin copolymer (B-2) having a melt flow rate (ASTM D1238, 230Â° C., 2.16 kg load) of 0.5 to less than 20 g/10 min; and 15 to 30% by weight of an inorganic filler (C) (the total of (A), (B-1), (B-2) and (C) is 100% by weight); 0.1 to 5.0 parts by weight of a modified polypropylene (D); and 0.1 to 1.0 parts by weight of a surface modifier (E).
