    Abstract: A composition comprising (A) from 30 wt % to 70 wt % of a propylene component including at least one propylene based polymer having a propylene content of at least 70.0 wt %, based on the total weight of the propylene based polymer, and a melt flow rate from 1.0 g/10 min to 100.0 g/10 min (ASTM D-1238 at 230° C., 2.16 kg); (B) from 1 wt % to 20 wt % of an ethylene component including at least one ethylene based polymer having an ethylene content of at least 85.0 wt %, based on the total weight of the ethylene based polymer, and a melt index from 0.1 g/10 min to 50.0 g/10 min (ASTM D-1238 at 190° C., 2.16 kg); (C) from 1 wt % to 40 wt % of an olefin block copolymer; and at least one of (D) from 1 wt % to 40 wt % of a polyolefin elastomer and (E) from 1 wt % to 30 wt % of a filler.

    Abstract: A composition comprising (A) from 10 wt % to 90 wt % of a propylene component including at least one propylene based polymer having a propylene content of at least 50.0 wt %, based on the total weight of the propylene based polymer, and a melt flow rate from 0.5 g/10 min to 200.0 g/10 min (ASTM D-1238 at 230° C., 2.16 kg); (B) from 1 wt % to 60 wt % of a polyolefin elastomer; (C) from 1 wt % to 20 wt % of a block composite comprising (i) an ethylene-propylene copolymer, (ii) an isotactic polypropylene copolymer, and (iii) a block copolymer including an ethylene-propylene soft block that has a same composition as the ethylene-propylene copolymer of the block composite and an isotactic polypropylene hard block that has a same composition as the isotactic polypropylene copolymer of the block composite; and (D) optionally, from 0.1 wt % to 10 wt % of an antioxidant.
