POLYPROPYLENE RESINE COMPOSITION

摘要

The present invention relates to a polypropylene resin composition and, more specifically, to a polypropylene resin composition which can not only obtain properties that basic components demand, but also reduce the weight since the weight is low, and has low linear expansion according to temperature variation, thereby easily used for interior and exterior materials for a vehicle. According to the present invention, provided is a polypropylene resin composition comprising: 40-97 wt% of a high crystalline polypropylene resin in which an isotactic peptide fraction is more than or equal to 96% by a C13-NMR method; 1-40 wt% of a rubber composition; 1-10 wt% of whisker; and 1-10 wt% of fine talc in which apparent density is less than or equal to 0.8 g/cm^3 and average particle size is less than or equal to 3μm.
