Abstract
The invention relates to a heterophasic propylene copolymer composition comprising a heterophasic propylene copolymer (A), optionally an ethylene-unit containing polymer (B) and an inorganic filler (C), wherein the heterophasic propylene copolymer (A) consists of a) a propylene-based matrix wherein the propylene-based matrix consists of a propylene homopolymer and/or a propylene copolymer consisting of at least 90 wt % of propylene units and at most 10 wt % of comonomer units selected from ethylene monomer units and α-olefin monomer units having 4 to 10 carbon atoms wherein the propylene-based matrix is present in an amount from 87.0 to 92.0 wt % based on the heterophasic propylene copolymer and b) a dispersed ethylene α-olefin copolymer, wherein the dispersed α-olefin copolymer is present in an amount from 8.0 to 13.0 wt % based on the heterophasic propylene copolymer and wherein the sum of the weight of the propylene-based matrix and the weight of the dispersed ethylene-α-olefin copolymer is 100 wt % based on the heterophasic propylene copolymer, wherein C) the inorganic filler is present in an amount of 0.10 to 4.9 wt % based on the composition wherein the melt flow index of the composition is in the range from 5.0 to 9.0 dg/min as determined according to ISO 1133:2011 at 230° C. and 2.16 kg and wherein the total amount of ethylene units in the composition are in the range from 5.7 to 10.0 wt % based on the composition.
