PURPOSE: A polypropylene resin composition is provided to be excellent in strengthening, shock absorbing ability, scratch resistance and good appearance. CONSTITUTION: A polypropylene resin composition comprises 96 parts by weight % of isotactic peptide fraction by a 40-98 parts by weight % of C-NMR method, 1-30 parts by weight % of rubber component and 1-30 parts by weight % of polypropylene nano master batch. The crystallized polypropylene resin has 1-80 g/10min of melt index and is polymer chosen from polypropylene homopolymer, propylene-ethylene copolymer, propylene 1 butene copolymer, propylene 1 hexene copolymer and propylene 4 methyl 1 pentene copolymer. |
