Patent ID: 10047218

Abstract:
The present invention relates to a polyolefin composition comprising a first heterophasic propylene copolymer and a second heterophasic propylene copolymer, wherein the first heterophasic propylene copolymer comprises: from 70-90 wt % of a first polypropylene having a melt flow index of from 55-85 g/10 min as measured according to ISO 1133 (2.16 kg and 230° C.), from 10-30 wt % of a first ethylene α-olefin copolymer having a melt flow index of from 2.5-5.0 g/10 min in accordance with ISO 1133 (2.16 kg and 230° C.), the respective amounts of first polypropylene and first ethylene α-olefin copolymer being based on the weight of the first heterophasic propylene copolymer and wherein the second heterophasic propylene copolymer comprises: from 60-85 wt % of a second polypropylene having a melt flow index of from 50-100 g/10 min as measured according to ISO 1133 (2.16 kg, 230° C.), from 15-40 wt % of a second ethylene α-olefin copolymer having a melt flow index of from 0.050-0.30 g/10 min in accordance with ISO 1133 (2.16 kg and 230° C.), the respective amounts of second polypropylene and second ethylene α-olefin copolymer being based on the weight of the second heterophasic propylene copolymer, and wherein a weight ratio of said first and second heterophasic propylene copolymer is from 1 to 10. The invention further relates to automotive parts comprising said composition and having good tiger stripe performance.
