Zusammenfassung:PROBLEM TO BE SOLVED: To obtain a lightweight polypropylene resin composition having excellent mechanical strengths and good impact resistance. SOLUTION: The polypropylene resin composition comprises 80-99 pts.wt. of a polypropylene (A) having 6-12 dl/g intrinsic viscosity [η] in decalin at 135°C and 1-20 pts.wt. of a filler (B) and contains a crystal nucleating agent (C) in an amount of preferably 0.01-1.0 pt.wt. based on 100 pts.wt. of the polypropylene resin composition and an elastomer (D) in an amount of preferably 1-20 pts.wt. based on 100 pts.wt. of the polypropylene resin composition.
