Patent ID: 8778471

Claim:
A propylene resin composition which contains as essential components thereof (A) an ethylene-propylene random copolymer having an ethylene content of 0.5 to 3.0 parts by mass; (B) an elastomer having an average particle diameter of 10 to 800 nm in an amount of 1 to 10 parts by mass based on 100 parts by mass of the ethylene-propylene random copolymer; and (C) an organic crystalline nucleating agent in an amount of 0.005 to 0.5 parts by mass based on 100 parts by mass of the ethylene-propylene random copolymer, and in which after kneading thereof, the kneaded propylene resin composition exhibit a melt flow rate (MFR) of 0.01 to 1.00 g/10 min, and the ethylene-propylene random copolymer (A) is a blend of 25 to 75 parts by mass of propylene homopolymer and 75 to 25 parts by mass of ethylene-propylene random copolymer.
