Abstract:
1. A polypropylene composition comprising a random propylene copolymer (R-PP), a high melt strength polypropylene (HMS-PP), a polypropylene (B) and a clarifier (C), wherein (a) the random propylene copolymer (R-PP) (b) the high melt strength polypropylene (HMS-PP) has a branching index g′ of less than 1.0, (c) the polypropylene (B) has a MFR (d) the clarifier (C) comprises at least one α-nucleating agent (N), and (e) the polypropylene composition has a MFR wherein further, (f) the polypropylene (B) is different to the random propylene copolymer (R-PP) at least in view of the melt flow rate MFR (g) the polypropylene (B) has a higher melt flow rate MFR (h) the polypropylene (B) has been visbroken.
