PROPYLENE RESIN COMPOSITION

PROBLEM TO BE SOLVED: To obtain a propylene resin composition, which is excellent in processability and weld appearance, by compounding a propylene/ethylene block copolymer, an ethylene/α-olefin/diene copolymerized rubber, talc and high-density polyethylene. SOLUTION: The resin composition comprises 100 parts by weight of a propylene-ethylene block copolymer, 1 to 50 parts by weight of an ethylene/α- olefin or ethylene/α-olefin/diene copolymerized rubber having an MFR value (at 230 deg.C under a load of 2.16 kg) of 0.05 to 1.2 g/10 minutes, 5 to 60 parts by weight of talc having an average particle size of 1.5 to 15 μm, and 0 to 10 parts by weight of high-density polyethylene having an MFR value (at 190 deg.C under a load of 2.16 kg) of 11 g/10 minutes. The propylene/ethylene block copolymer contains 60 to 95 wt.% of a crystalline polypropylene moiety and 5 to 40 wt.% of a propylene/ethylene random copolymer moiety having an ethylene content of 30 wt.% or more, and has a swell index of 1.4 or below.
