Abstract: Relates to a thermoplastic polyolefin composition including from 50 wt % to 90 wt % of a polypropylene having a melt flow rate from 10 g/10 min to 200 g/10 min; from 10 wt % to 45 wt % of an ethylene-α-olefin copolymer having a melt flow rate from 0.1 g/10 min to 10 g/10 min; from 0.1 wt % to 5 wt % of a propylene-based elastomer having a melt flow rate from 0.1 g/10 min to 10 g/10 min; wherein the melt flow rate of the propylene-based elastomer is between the melt flow rate of the polypropylene and the melt flow rate of the ethylene-α-olefin copolymer, and wherein an amount of the ethylene-derived units in the propylene-based elastomer is between an amount of ethylene-derived units in the polypropylene and an amount of the ethylene-derived units in the ethylene-α-olefin copolymer.
