Abstract:
The invention relates to composition comprising (A) a propylene-based polymer, (B1) a first elastomer of ethylene and α-olefin comonomer having 4 to 10 carbon atoms, (B2) a second elastomer of ethylene and α-olefin comonomer having 4 to 10 carbon atoms and (C) an inorganic filler, wherein (B1) the first elastomer has a density of 0.850 to 0.890 g/cm3 and a melt flow index of 5 to 50 dg/min measured in accordance with ASTM D1238 using a 2.16 kg weight and at a temperature of 190° C., wherein (B2) the second elastomer has a density of 0.850 to 0.890 g/cm3 and a melt flow index of 0.55 to 4 dg/min measured in accordance with ASTM D1238 using a 2.16 kg weight and at a temperature of 190° C., wherein the total amount of (B1) the first elastomer and (B2) the second elastomer is 2 to 30 wt % based on the total composition, wherein the amount of (C) the inorganic filler is 0.1 to 30 wt % based on the total composition.
