ABSTRACT:
A ternary molding composition is formed of an admixture of ethylene-propylene copolymer, propylene polymer, and polyethylene and contains 30-45% by weight of a partially crystalline ethylene-propylene copolymer with an ethylene content of at least 65% by weight; a melt index MFI (230/5) of 0.7-2.0 g/10 min, and a tensile strength higher than 5.0 N/mm.sup.2 ; 35-65% by weight of propylene polymer with a melt index MFI (230/5) of 15-50 g/10 min, and 3-30% by weight of polyethylene with a melt index MFI (230/5) of 15-50 g/10 min, said molding composition having a melt index MFI (230/5) of at least 8 g/10 min and a tensile strength of at least 15 N/mm.sup.2 and an elongation at yield of at least 450%.
