The present invention concerns heterophasic propylene copolymers, comprising a propylene homopolymer (PPH) and an ethylene-propylene rubber (EPR), having a very broad molecular weight distribution, a well-defined total ethylene content and a specific intrinsic viscosities of the ethylene-propylene rubber (EPR). The invention further concerns the process to produce such heterophasic propylene copolymers. The heterophasic propylene copolymers of the present invention are particularly suited for pails, pallets, IBCs and crates. In particular, the heterophasic propylene copolymers of the present invention are characterized by an improved resistance to creep.

The thermoset, phase-separated polyurethane material of the flexible skin layer is produced from a reactive mixture which is made of one or more isocyanate compounds and isocyanate reactive compounds which include one or more polyol compounds, flexibilizers, chain extenders and/or crosslinkers and amine-initiators. Apart from at least one crosslinking amine-initiator, these amine-initiators further include at least one extender amine-initiator.
