POLYPROPYLENE RESIN COMPOSITION

摘要

The present invention relates to a polypropylene resin composition which is characterized by including (A) 40-96 wt% of a high crystalline polypropylene resin having isotactic peptide fraction of 96% or more by C^13-NMR method; (B) 1-30 wt% of a rubber component; (C) 1-10 wt% of a nanoclay master batch; (D) 1-10 wt% of whisker; and (E) 1-10 wt% of fine talc. Provided in the present invention is a polypropylene resin composition which has low specific gravity, while having ameliorated hardness and impact properties, and low linear expansion coefficient, thereby having physical properties proper to be widely applied as a material for a vehicle exterior with improved dimensional stability.
