Patent ID: 8318863

Claim:
A foaming polypropylene resin composition comprising: 50 to 95 parts by weight of a polypropylene resin (A) and 5 to 50 parts by weight of an ethylene/α-olefin having 3-10 carbon atoms copolymer (B) (wherein the total of (A) and (B) is 100 parts by weight), the ethylene/α-olefin having 3-10 carbon atoms copolymer (B) comprising: a higher molecular weight component (B-H) having a melt flow rate (MFR 190 ) of 1 to 10 g/10 min as measured in accordance with ASTM D-1238 (190° C., 2.16 kg load), and a lower molecular weight component (B-L) having a melt flow rate (MFR 190 ) of 20 to 50 g/10 min as measured in accordance with ASTM D-1238 (190° C., 2.16 kg load); the weight ratio between (B-H) and (B-L), (B-H):(B-L), being in the range of 6:4 to 2:8.
