Patent ID: 8003725

Claim:
A hetero-phase polyolefin composition comprising: a) 30 to 99.7 wt % of a polypropylene-based TPO comprising at least 50 wt % propylene and at least 10 wt % ethylene wherein the polypropylene-based TPO comprises a matrix having a T m of 110° C. or more and a dispersed phase having a T g of −20° C. or less, and b) 0.1 to 20 wt % of one or more non-functionalized plasticizer(s) (NFP), c) 5 to 50 wt % of one or more filler(s); and d) 5 to 40 wt % of at least one ethylene copolymer having a density of less than 0.90 g/cm 3 ; based upon the weight of the composition, and having: i) an melt flow rate (MFR) of 5 dg/min or more, and ii) a flexural modulus of 1100 MPa or more, and iii) a notched Charpy impact strength at −30° C. of 1 kJ/m 2 or more or a notched Izod impact strength at −18° C. of 50 J/m or more; and wherein when the composition is injection molded the distance from the gate to the first visible flow mark is 5 in or more.
