Abstract:
The present invention relates to a polypropylene composition comprising
a multimodal propylene random copolymer (A) with at least one comonomer selected from alpha-olefins with 2 or 4 to 8 carbon atoms and
a nucleating agent (B),
wherein the polypropylene composition has a Charpy Notched Impact Strength at 23° C. of at least 30 kJ/m2, determined according to ISO 179/1eA:2000 using notched injection moulded specimens, a process for producing said polypropylene composition, an article comprising said polypropylene composition and the use of said polypropylene composition for the production of an article.
