Patent ID: 7279526

Claim:
A heterophasic propylene polymer composition comprising the following components: (i) 60 to 90% wt, relative to the total weight of components (i), (ii) and (iii), of a propylene polymer matrix comprising a propylene homopolymer and a random propylene copolymer, said propylene polymer matrix having an ethylene content of no more than 5% wt; (ii) 5 to 30% wt, relative to the total weight of components (i), (ii) and (iii), of an ethylene-propylene copolymer elastomer comprising 25 to 45% wt % of ethylene; and (iii) 5 to 25% wt, relative to the total weight of components (i), (ii) and (iii), of an ethylene copolymer plastomer having a density of not more than 910 kg/m 3 and a melt flow rate MFR 2.16 (190° C.) of at least 0.5 g/10 minutes at 190° C. under a weight of 2.16 kg, wherein the random propylene copolymer comprises a repeating unit derived from ethylene or a C 4-10 unsaturated monomer.
