WIPO Patent Application WO/2017/164343
Kind Code:
A1
Abstract:
Provided is a polypropylene resin composition which is capable of providing an injection foam molded body that has excellent impact resistance and good foam state. This composition contains a conjugated diene-modified polypropylene resin (A) which is a conjugated diene-modified propylene-ethylene block copolymer having a melt flow rate of 1 g/10 min or more but less than 80 g/10 min and a polypropylene resin (B) which is a propylene-ethylene block copolymer having a melt flow rate of 1 g/10 min or more but less than 80 g/10 min. This composition is configured such that: the content of the ethylene component in the component (A) is 1% by weight or more; the content of the component (A) is 1-49% by weight and the content of the component (B) is 51-99% by weight relative to 100% by weight of the total of the component (A) and the component (B); and the melt tension of the composition is 0.1 gf or more but less than 2.0 gf.
