POLYPROPYLENE-BASED RESIN COMPOSITION AND INJECTION MOLDED ARTICLE CONSISTING OF THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a polypropylene-based resin composition excellent in collision resistant performance and an injection molded article consisting of the same. SOLUTION: This polypropylene-based resin composition consists of (A) 75-95 wt. % propylene-ethylene block copolymer consisting of (A1) 75-60 wt. % propylene homopolymer part and (A2) 25-40 wt. % propylene-ethylene random copolymer part, and (B) 5-25 wt. % inorganic filler. Provided that the total amount of (A) the propylene-ethylene block copolymer and (B) the inorganic filler is set as 100 wt. %. The injection-molded article consists of the propylene-based resin.
