THERMOPLASTIC RESIN COMPOSITION EXCELLENT IN APPEARANCE OF MOLDED PRODUCT AND IMPACT RESISTANCE AT LOW TEMPERATURE

摘要

PROBLEM TO BE SOLVED: To obtain a thermoplastic resin composition having good molding processability at the time of injection molding, excellent in appearance such as flow mark, especially good in low temperature embrittlement characteristics and suitable for an injection molded product such as an automotive part. SOLUTION: This thermoplastic resin composition is constituted of the following components (A) to (C): component (A): 25-95 wt.% propylene-ethylene block copolymer having >=25 g/10 min melt flow rate (MFR); component (B) : 5-40 wt.% ethylene-α-olefin-nonconjugated diene copolymer rubber wherein the number of carbons in theα-olefin is >=4; and component (C): 0-33 wt.% talc having <=10μm average particle diameter.
