  • Polypropylene composition with excellent stiffness and impact strength
    Patent number: 11845857
    Abstract: The present invention is directed to a polypropylene composition (C) comprising an ?-nucleated heterophasic composition (HECO) comprising a (semi)crystalline polypropylene (PP1), an elastomeric ethylene/propylene copolymer (EPR) and a first ?-nucleating agent (NU1), an impact modifier comprising a polyethylene (PE) being a copolymer of ethylene and a C4-C12 ?-olefin and a second ?-nucleating agent (NU2). The present invention is further directed to a method for preparing said polypropylene composition (C) and an article comprising said polypropylene composition (C). The present invention is also directed to the use of a composition comprising a polyethylene (PE) being a copolymer of ethylene and a C4-C12 ?-olefin and an ?-nucleating agent (NU2) as an impact modifier.
