| 主权项 | 1. A composition comprising: (I) 60 to 92.5 wt % of a first component which is a polypropylene polymer comprising a) 40 to 85 wt % of a propylene homopolymer A having a melt flow rate (MFR2) between 0.01 and 300 g/10 min, andb) 15 wt % or more of at least one propylene ethylene copolymer; and (II) 2.5 to 30 wt % of a second component comprising at least one ethylene C1-C4-alkyl (meth)acrylate polymer; and (III) 5 to 25 wt % of at least one filler, wherein the difference between radial and tangential shrinkage of the composition is less than 0.1 percentage points. | ||
