RESIN COMPOSITION FOR INJECTION MOLDING

摘要

PROBLEM TO BE SOLVED: To provide a resin composition for injection molding, which provides a molded article that has excellent impact strength at low temperatures and is free from the occurrence of flow marks.

SOLUTION: The resin composition for injection molding contains: 70-90 pts.wt of a polypropylene-based resin (I); 5-25 pts.wt of an ethylene-α-olefin copolymer (II) that has a melt tension as determined at 160°C of 50 to 300 mN; and 5-25 pts.wt of a low density polyethylene (III) that is produced by high-pressure radical polymerization (provided that (I)+(II)+(III)=100 pts.wt).
