Abstract (en)
[origin: WO2013041507A1] Heterophasic propylene copolymer (HECO) comprising (a) a matrix (M) being a polypropylene (PP), said polypropylene (PP) comprises at least three polypropylene fractions (PP1), (PP2) and (PP3), the three polypropylene fractions (PP1), (PP2) and (PP3) differ from each other by the melt flow rate MFR2 (230 °C) measured according to ISO 1133, and (b) an elastomer (E) dispersed in said matrix (M), wherein the elastomer (E) is included in an amount of 20 wt.-% or more, based on the weight of the heterophasic propylene copolymer (HECO).
