Use of polypropylene compositions for automobile parts

Use of a polypropylene composition comprising (1) 55 to 60 wt .-% comprising on relative the composition of propylene / ethylene block copolymer comprising 85 to 96 wt .-% of (A) a component which has an intrinsic viscosity at 135 ° C in decalin (η) of 0.6 to 0.95 dl / g, has a stereoregularity index of at least 98.8%, and in p-xylene at 25 ° C and is insoluble in boiling n-heptane; and 4 to 15 wt .-% of (B) a component having an intrinsic viscosity at 135 ° C in decalin (η) from 5 to 11 dl / g, 15 to 37 wt .-% of a unit containing the ethylene is derived, and is soluble at 25 ° C in p-xylene; wherein the block copolymer (C) wt .-% at most 15 - having content of polyethylene component and a melt index at 230 ° C and at 2.16 kgf from 110 to 200 g / 10 minutes, (2) 20 to 25 wt .-% based on the relative composition of rubber, which (D) a styrene / ethylene / propylene / styrene block copolymer and / or a styrene / ethylene / 1-butene / styrene block copolymer, each copolymer a melt flow rate ...
