PURPOSE: A polypropylene resin composition is provided to reduce the size and weight of a product thereof, and to have sufficient scratch resistance and impact resistance for a vehicle door trim. CONSTITUTION: A polypropylene resin composition comprises: 50-99 weight% of highly crystalline polypropylene resin which has a melt index of 5-90 g/10minutes(230 deg. C) and an isotactic index of 98% or more; 0.1-10 weight% of nanoclay master batch; 0.1-20 weight% of thermoplastic elastomer; 0.01-10 weight% of scratch-resisting agent; and 0.01-10 weight% of nucleating agent. The highly crystalline polypropylene resin comprises a propylene mono polymer, a copolymer of the propylene and ethylene, or a mixture thereof. |
