Beschreibung
Zusammenfassung:	The invention relates to a composition comprising (A) a propylene-based polymer, (B) an elastomer of ethylene and α-olefin comonomer having 4 to 10 carbon atoms and (C) an inorganic filler,wherein (A) the propylene-based polymer has a melt flow index of 60 to 150 dg/min measured according to ASTM D1238 (2.16 kg/230° C.) andwherein (B) the elastomer has a density of 0.840 to 0.865 g/cm3,wherein (B) the elastomer has a melt flow index of 3 to 13 dg/min measured in accordance with ASTM D1238 using a 2.16 kg weight and at a temperature of 190° C.,wherein the amount of (B) the 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.
