Abstract
The invention relates to a heterophasic propylene copolymer comprising a matrix phase comprising a propylene polymer and a dispersed phase comprising an ethylene-α-olefin elastomer comprising ethylene and at least one Cto Colefin, wherein the propylene polymer has a melt flow index of at least 200 dg/min or at least 150 dg/min as determined by IS01 133:2005 at 230° C. and 2.16 kg, wherein the propylene polymer has an intrinsic viscosity IVand the ethylene-α-olefin elastomer has an intrinsic viscosity IVwhere the ratio of IV/IVis 3-7, wherein the copolymer comprises 8-20 wt % or 20-30 wt % of the ethylene-a-olefin elastomer, wherein the ethylene-a-olefin elastomer of the dispersed phase comprises 10-55 wt % of ethylene.
