Zusammenfassung: | Random propylene copolymer comprising
(a) a first polypropylene being a first random propylene copolymer, said first random propylene copolymer has a melt flow rate MFR 10 (230 C) of not more than 1.5 g/10min,
(b) a second polypropylene being a first propylene homopolymer or a second random propylene copolymer,
(c) a third polypropylene being a second propylene homopolymer or a third random propylene copolymer, said third random propylene copolymer has a comonomer content of 0.5 to 3.5 wt.-%,
wherein further
(i) the first polypropylene differ from the second polypropylene and the third polypropylene by the melt flow rate MFR 2 (230 C) and/or by the comonomer content,
(ii) the second polypropylene differ from the third polypropylene by the melt flow rate MFR 2 (230 C) and/or by the comonomer content [wt.-%], and
(iii) the random propylene copolymer (R-PP) has a melt flow rate MFR 2 (230 C) of 0.05 to 10.00 g/10min. |
