  • Publication number: 20240026106
    Abstract: A polymer composition includes a) ?10 wt % and ?60 wt % of a high melt strength polypropylene, b) ?10 wt % and ?35 wt % of a polyethylene, c) ?10 wt % and ?60 wt % of a first polypropylene, wherein the first polypropylene is chosen from the group of propylene homopolymers, propylene copolymers and/or mixtures thereof, and d) ?0 wt % and ?60 wt % of a second polypropylene, wherein the sum of the high melt strength polypropylene, the first polypropylene and the second polypropylene is ?60 wt % based on the sum of the weight of the high melt strength polypropylene, the polyethylene, the first polypropylene and the second polypropylene. The polyethylene has a density ?940 kg/m3 and ?970 kg/m3 as determined according to ISO 845 (2006).
