A polypropylene composition made from or containing: (a) 65 to 85 weight % of a crystalline propylene polymer having an amount of isotactic pentads (mmmm), measured by 13C-MNR on the fraction insoluble in xylene at 25° C. higher than 97.0 molar % and a polydispersity index from 3 to 15; (b) 5 to 25 weight % of an elastomeric copolymer of ethylene and propylene, having an amount of recurring units deriving from ethylene ranging from 30 to 70 weight %, and being partially soluble in xylene at ambient temperature; wherein the fraction soluble in xylene at ambient temperature having an intrinsic viscosity value from 3 to 10 dl/g; and (c) 5 to 25 weight % of recycled polyethylene (r-PE) having a melt flow rate (190° C./2.16 Kg) from 0.1 to 10 g/10 min, wherein the polypropylene composition having a melt flow rate (ISO 1133 230° C./2.16 kg) higher than 3.0 to 15 g/10 min.
A polypropylene composition comprising:
