Moudling composition

摘要

Polyolefin composition comprising a heterophasic propylene copolymer and glass material, wherein said heterophasic propylene copolymer has • a xylene cold soluble fraction in the range of 25 to 50 wt.-%, and • a comonomer content in the range of 10.0 to 15.0 wt.-%, wherein further the xylene cold soluble fraction of the heterophasic propylene copolymer has a comonomer content in the range of 20 to 30 wt.-% and the polyolefin composition has a melt flow rate MFR2 (230° C.) of 2.0 to 15.0 g/10 min.

1. Polyolefin composition comprising:
(a) at least 50 wt. % based on the polyolefin composition of a heterophasic propylene copolymer (RAHECO) comprising a matrix (M) being a random propylene copolymer (R-PP) and an elastomeric propylene copolymer (E) dispersed in said matrix (M), wherein said heterophasic propylene copolymer (RAHECO) has
(a1) a xylene cold soluble fraction (XCS) determined according ISO 16152 (25° C.) in the range of 25 to 50 wt. % based on the heterophasic propylene copolymer (RAHECO), and(a2) a comonomer content in the range of 10.0 to 15.0 wt. % based on the heterophasic propylene copolymer (RAHECO), wherein further the xylene cold soluble fraction (XCS) of the heterophasic propylene copolymer (RAHECO) has
(a3) a comonomer content in the range of 20 to 30 wt. % based on the xylene cold soluble fraction (XCS) of the heterophasic propylene copolymer (RAHECO) and(a4) an intrinsic viscosity (IV) determined according to DIN ISO 1628/1 (in Decalin at 135° C.) in the range of 0.8 to below 2.0 dl/g, (b) at least 5 wt.-% based on the polyolefin composition of a filler (F) being a glass material (GM), and (c) a compatibilizer (C), wherein the polyolefin composition has a melt flow rate MFR2 (230° C.) measured according to ISO 1133 of 2.0 to 15.0 g/10 min.
