Abstract
The present invention provides a polypropylene resin composition including (A) about 60 to 80% by weight of a base resin selected from the group consisting of a high crystalline polypropylene, a propylene-ethylene copolymer, and a mixture thereof; (B) about 2 to 8% by weight of a styrene-ethylene/butene-styrene elastomer; (C) about 6 to 10% by weight of an ethylene-octene elastomer; (D) about 5 to 10% by weight of whisker; (E) about 2 to 8% by weight of talc; (F) about 1 to 3% by weight of a modified polypropylene grafted with maleic anhydride; (G) about 1 to 5% by weight of a vinyl-based acetal compatibilizer; and (H) about 1 to 3% by weight of a slipping agent containing a siloxane-based compound and an amide-based compound, with respect to the total weight of polypropylene. Polypropylene resin compositions according to the present invention can exhibit excellent physical properties such as high stiffness and impact resistance even though formed into a thin film. Hence, the polypropylene resin composition of the present invention can be effectively applied as a vehicle interior material such as a door trim, a pillar trim, a tail gate, and further can contribute to reducing weight of a vehicle.
