Patent ID: 8709561

Claim:
A polypropylene composition comprising a melt flow rate MFR 2 (230° C.) measured according to ISO 1133 of at least 2.0 g/10 min, said polypropylene composition comprising a propylene copolymer (C-PP), a high melt strength polypropylene (HMS-PP), and an α-nucleating agent (N), wherein the propylene copolymer (C-PP) (a) has a comonomer content of equal to or below 7.0 wt.-%, the comonomers are ethylene and/or at least one C 4 to C 12 α-olefin, (b) comprises two propylene copolymer fractions (A) and (B), wherein the comonomer content of the first propylene copolymer fraction (A) is in the range of 1.0 to 4.5 wt.-% and the comonomer content of the first propylene copolymer fraction (A) is lower compared to the comonomer content of the second propylene copolymer fraction (B).
