Abstract
Disclosed is a thermoplastic polyolefin composition useful in automotive components comprising at least a polypropylene having a melting point temperature (T) 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 Tof 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/inat 22° C. (533 to 2,132 J/m), and between 1.0 to 12 ft-lb/inat −29° C. (53 to 636 J/m).
