The present invention relates to plasticized polyolefin compositions comprising a polyolefin and a non-functionalized hydrocarbon plasticizer.

Plasticized polyolefin compositions

This invention relates to hetero-phase polyolefin compositions comprising: a) 30 to 99.7 wt% of a polypropylene-based TPO comprising at least 50 wt% propylene and at least 10 wt% ethylene, and b) 0.1 to 20 wt% of one or more non-functionalized plasticizer, and c) 0.2 to 50 wt% of one or more filler; based upon the weight of the composition, and having: i) an MFR of 5 dg/min or more, and ii) a flexural modulus of 500 MPa or more, and iii) a notched Charpy impact strength at -30°C of 1 kJ/m2 or more or a notched Izod impact strength at -18°C of 50 J/m or more. These compositions are especially useful in applications such as automotive parts that demand both high stiffness and high impact toughness, as well as good processibility during fabrication.

Plasticized hetero-phase polyolefin blends

The present invention relates to fibers and nonwovens made from plasticized polyolefin compositions comprising a polyolefin, a non-functionalized hydrocarbon plasticizer and a slip agent.

Polypropylene based fibers and nonwovens

The invention describes a cable with recyclable covering, particularly for transporitng or distributing medium or high voltage energy, in which at least one covering layer is based on thermoplastic polymer material comprising a propylene homopolymer or a copolymer of propylene with ethylene or an .prop.-olefin other than propylene in mixture with a dielectric liquid. The cable of the invention possesses superior mechanical and electrical properties, including high dielectric strength, in particular enabling it to be used at high operating temperature.
