Zusammenfassung:A propylene polymer composition made from or containing:A) 65 to 95 wt % of a polypropylene composition having a MFR (230° C./2.16 kg) from 0.2 to 1.2 g/10 min, made from or containing(a) 15 to 45 wt % of a fraction made from or containing a propylene homopolymer, or a copolymer of propylene with ethylene or a CH2═CHR alpha-olefin, having a fraction insoluble in xylene at 25°° C. for at least 90 wt %; and(b) 55 to 75 wt % of a fraction made from or containing a copolymer of ethylene with propylene or CH2═CHR alpha-olefins, containing ethylene derived-units in a quantity lower than 40 wt %, and having solubility in xylene at 25° C. greater than 60 wt %, and(B) 5 to 35 wt % of recycled styrene block copolymer having a melt flow rate (190° C./2.16 Kg) from 0.5 to 15 g/10 min,wherein the propylene polymer composition having a MFR from 0.4 to 1.4 g/10 min.
