Abstract:
Automotive interior element comprising a polypropylene composition comprising (percent by weight): A) from 60% to 90% of a propylene homopolymer having: i) a polydispersity Index (P.I.) value of from 3.5 to 10.0; ii) a fraction insoluble in xylene at 25° C., higher than 90%; and iii) a MFR L (Melt Flow Rate according to ISO 1133, condition L, i.e. 230° C. and 2.16 kg load) from 50 to 200 g/10 min; B) from 10% to 40%; of a copolymer of propylene with from 30% to 60% of ethylene derived units; the composition having an intrinsic viscosity of the fraction soluble in xylene at 25° C. comprised between 2.5 and 4.0 dl/g; a MFR L (Melt Flow Rate according to ISO 1133, condition L, i.e. 230° C. and 2.16 kg load) from 15 to 100 g/10 min and all the three values of carbon emission measured according to VDA 227 (C-emission) are lower than 30.0 μgC/g; wherein the values of carbon emission are measured in the ex reactor propylene composition.
