POLYPROPYLENE COMPOSITION AND THERMOFORMED SHEET THEREOF

摘要

The present invention relates to a polypropylene composition for thermoforming comprising: from 50 % by weight to at most 90 % by weight of a polypropylene A, wherein polypropylene A is a polypropylene random copolymer, based on the total weight of the polypropylene composition; and from 10 % by weight to at most 50 % by weight of a polypropylene B, wherein polypropylene B is a polypropylene homopolymer, based on the total weight of the polypropylene composition; wherein the melt flow index of polypropylene B is at most 1.0 g/10min, as measured according to the method of standard ISO 1133, condition M, at 230 °C and under a load of 2.16 kg; and wherein the ratio of the melt flow index of polypropylene A to the melt flow index of polypropylene B is at least 80.
