Abstract: Disclosed is a thermoplastic polyolefin composition useful in automotive components comprising at least a polypropylene having a melting point temperature (Tm) of greater than 130° C. and a melt flow rate (230° C./2.16 kg) within the range from 10 g/10 min to 80 g/10 min; an amorphous ethylene-propylene copolymer comprising within the range from 40 wt % to 80 wt % ethylene derived units and having a melt flow rate (230° C./2.16 kg) within the range from 0.1 g/10 min to 20 g/10 min; and a propylene-based elastomer having within the range from 5 to 25 wt % ethylene derived units and having a Tm of less than 110° C. The composition only partially breaks or there is no break at −29° C. (ASTM D256) with Notched Izod Force of between 10 to 40 ft-lb/in2 at 22° C. (533 to 2,132 J/m2), and between 1.0 to 12 ft-lb/in2 at −29° C. (53 to 636 J/m2).

Abstract: The present invention is related to a grip composition comprising 5 to 10 wt % of a polymer blend modifier, having a weight average molecular weight of 10,000 to 100,000 g/mole, 65 to 75 wt % of a propylene-based elastomer, having a weight average molecular weight of 100,000 to 300,000 g/mole, and a mineral powder. The polymer blend modifier comprises a first propylene-based polymer and a second propylene-based polymer, where the first and second propylene-based polymers are different and are individually selected from a homopolymer of propylene or a copolymer of propylene and ethylene or a C4 to C10 alpha-olefin. The composition further comprises 5 to 10 wt % of a propylene polymer, which is a homopolymer of propylene or a copolymer of propylene units with from 0.5 to 4 wt % ethylene or C4 to C10 alpha-olefin comonomer derived units.

Abstract: A bimodal polypropylene composition of at least a high molecular weight, predominantly isotactic, narrow molecular weight distribution polypropylene having a heat of fusion of 70 to 100 J/g, and a low molecular weight, predominantly isotactic, narrow molecular weight distribution polypropylene having a heat of fusion of 70 to 100 J/g, wherein the high molecular weight polymer and low molecular weight polymer are sufficiently miscible to impart a single glass transition temperature and a single melting point to the polymer blend, has improved processibility and stiffness compared to a single narrow molecular weight distribution isotactic polypropylene of the average of the components.

Abstract: Foam pellets comprising a thermoplastic vulcanizate (TPV) and thermo-expandable microspheres, the foam pellet having a specific gravity of 0.2 to 1.0 and the TPV being composed of an at least partially vulcanized rubber component and a thermoplastic component. The foam pellets may be subsequently processed to form various foam articles without the need to include a foaming agent during processing.
