ABSTRACT:
A ternary molding composition is formed of an admixture of a modified ethylene-propylene copolymer, a propylene polymer and polyethylene and contains 35-50% by weight of a modified ethylene-propylene copolymer, which is prepared by the polymerization of an ethylene-propylene copolymer onto polyethylene, with the ethylene content of the ethylene-propylene copolymer being at least 65% by weight and the modified copolymer having a melt index MFI (230/5) of 0.8-2.0 g/10 min; 30-60% by weight of polypropylene with a melt index MFI (230/5) of 25-65 g/10 min and/or propylene-ethylene copolymer with a melt index MFI (230/5) of 15-50 g/10 min, and 3-30% by weight of polyethylene, wherein the polyethylene block of the modified ethylene-propylene copolymer can be attributable to the quantity of polyethylene contained in said composition.
