摘要: A polypropylene composition for injection-molded drainage systems comprising 78-84 wt % of a crystalline propylene polymer, 8 to less than 13 wt % of an elastomeric copolymer and 8 to less than 13 wt % of polyethylene. The said composition exhibits a flexural modulus value higher than 1400 MPa, a melt flow rate (MFR), determined according to ISO method 1133 (230° C. and 2.16 kg), of from 1.5 to 5.0 g/10 min, and a value of Izod impact resistance at 0° C. of more than 6 kJ/m2 according to ISO method 180/1A.
