发明名称 IMPROVED SCRATCH RESISTANCE POLYPROPYLENE AT HIGH FLOW
摘要 Injection molded article comprising at least 60 wt.-% of a heterophasic propylene copolymer, said polymer comprises a matrix being a polypropylene, said polypropylene comprises at least three polypropylene fractions, the three polypropylene fractions differ from each other by the melt flow rate and at least one of the three polypropylene fractions has a melt flow rate in the range of 1.0 to 20.0 g/10 min, and an elastomeric propylene copolymer dispersed in said matrix, wherein said heterophasic propylene copolymer has a melt flow rate of equal or more than 20.0 g/10 min and the amorphous phase of the xylene cold soluble fraction of the heterophasic propylene copolymer has an intrinsic viscosity of equal or higher than 2.0 dl/g.
