ИСТИНА

A heterophasic polypropylene resin comprising a polypropylene homopolymer phase (A) and an ethylene-propylene copolymer phase (B) dispersed within phase (A), in which the xylene-soluble fraction of the polypropylene resin heterophasic is in the range of 20 to less than 50% by weight; the heterophasic polypropylene resin has an MFR2 of 0.01 to 50 g / 10 min; the ethylene content of the xylene soluble fraction of the heterophasic polypropylene resin is in the range of at least 20% by weight to less than 50% by weight; MFR2 (insoluble in xylene) is 0.2 g / 10 min or less; and in which the MFR2 (XS) / MFR2 (insoluble in xylene)> = 5, preferably> = 10.
