ИСТИНА

A heterophasic polypropylene resin comprising a polypropylene homopolymer matrix phase (A) and an ethylene-propylene copolymer phase (B) dispersed within the matrix, wherein the xylene soluble fraction of the heterophasic polypropylene resin is in the range 20 to less than 50 wt%; the heterophasic polypropylene resin has an MFR2 of 0.01 to 50 g/10min; the ethylene content of the xylene soluble fraction of the heterophasic polypropylene resin is in the range of at least 20 wt% to less than 50 wt%; the heterophasic polypropylene resin has a notched charpy impact strength at -20 DEG C of at least 25 kJ/m2, preferably at least 50 kJ/m2 of notch charpy impact strength; and wherein the MFR2(Matrix)/MFR2(XS) >= 5, preferably >=10.
