Composition comprising heterophasic propylene copolymer

A composition comprising a heterophasic propylene copolymer (A), glass fibers (B) and an ethylene-α-olefin copolymer (C), wherein the α-olefin is chosen from the group of α-olefins having 3 to 12 carbon atoms,

• 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-α-olefin copolymer consisting of at least 85 wt % of propylene and at most 15 wt % of α-olefin, based on the total weight of the propylene-based matrix, and
• wherein the propylene-based matrix is present in an amount of 55 to 75 wt % based on the total heterophasic propylene copolymer, and
• (b) a dispersed ethylene-α-olefin copolymer,
• wherein the dispersed ethylene-α-olefin copolymer is present in an amount of 45 to 25 wt % based on the total heterophasic propylene copolymer, and
• wherein the sum of the total amount of propylene-based matrix and total amount of the dispersed ethylene-α-olefin copolymer in the heterophasic propylene copolymer is 100 wt % based on the heterophasic propylene copolymer,
• wherein the heterophasic propylene copolymer has a flexural modulus of less than 1000 MPa as determined at 23° C. in the parallel direction according to ASTM D790 Procedure B on a sample of 65×12.7×3.2 mm.
• wherein the dispersed ethylene α-olefin copolymer (b) has an average rubber particle size d50 of at most 1.15 μm as determined by scanning electron microscopy, and
• wherein the total amount of (b) the dispersed ethylene-α-olefin copolymer in the heterophasic propylene copolymer (A) and the ethylene-α-olefin copolymer (C) is 30 to 60 wt % based on the total composition.
