POLYPROPYLENE BASED RESIN COMPOSITION AND INJECTION-MOLDED PRODUCT THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a polyolefin based resin composition for injection molding which contains woody materials and exhibits excellent impact resistance, and an injection-molded product thereof. SOLUTION: The polypropylene based resin composition containing woody materials comprises (A) 16-35 pts.wt. of a polyolefin having a melt flow rate under a load of 2.16 kg at 230°C (MFR: JIS-K-6758) of 20-200 g/10 min, (B) 40-80 pts.wt. of a lignocellulosic or cellulosic substance, (C) 1-10 pts.wt. of a modified polyolefin and (D) 3-25 pts.wt. of an ethylene/α-olefin elastomer having a density of at most 0.875. The injection-molded article thereof is also provided. COPYRIGHT: (C)2005,JPO&NCIPI
