PROBLEM TO BE SOLVED: To provide a polypropylene resin composition capable of producing a molded product that has a low brittle temperature and is excellent in low-temperature impact resistance, in the molded product whose weight is desired to be reduced.SOLUTION: A polypropylene resin composition comprises: 35 to 70 wt.% of a propylene-based polymer (component A) or a mixture (component A') of the propylene-based polymer; 10 to 25 wt.% of an ethylene-α-olefin copolymer (component B); 4 to 15 wt.% of a talc (component C); 0.5 to 5 wt.% of a modified polyolefin resin (component D); and 5 to 20 wt.% of glass particle hollow sphere powder (component E), wherein the total quantity of (component A) or (component A'), (component B), (component C), (component D), and (component E) is 100 wt.%. An injection-molded product formed by the polypropylene resin composition is also provided. |
