Polypropylene resin composition |
摘要 |
A polypropylene resin composition comprising: 95 to 80% by weight of a polypropylene resin (A) consisting of a propylene-ethylene block copolymer (i) composed of a propylene homopolymer portion having an intrinsic viscosity [eta]AP of not more than 1.3 dl/g, and a propylene-ethylene random copolymer portion having an intrinsic viscosity [eta]AEP of not more than 3.0 dl/g, or a mixture (ii) of the propylene-ethylene block copolymer (i) and a propylene homopolymer; and 5 to 20 by weight of a propylene-ethylene block copolymer (B) having a propylene-ethylene random copolymer portion having an intrinsic viscosity [eta]BEP of from 8.0 to 15 dl/g, wherein the polypropylene resin composition has a melt flow rate (MFR) of from 5.0 to 150 g/10 min. and the sum of the (A) and (B) is 100% by weight.
