  • Foamable polypropylene composition
    Patent number: 12084564
    Abstract: The present invention relates to a polypropylene composition, an injection molded article comprising the polypropylene composition, a foamed article comprising the polypropylene composition as well as the use of said polypropylene composition for reducing the stiffness reduction factor of a foamed injection molded article by at least 200 as determined by the difference of the flexural modulus measured according to ISO 178 of the non-foamed and foamed injection molded article.
    Type: Grant
    Filed: October 2, 2019
    Date of Patent: September 10, 2024
    Assignee: BOREALIS AG

  • Foamable polypropylene compositions
    Patent number: 11396593
    Abstract: The present invention relates to a polypropylene composition, an injection molded article comprising the polypropylene composition, a foamed article comprising the polypropylene composition as well as the use of a polypropylene homopolymer (H-PP1) for reducing the 5stiffness reduction factor of a foamed injection molded article by at least 40 as determined by the difference of the flexural modulus measured according to ISO 178 of the non-foamed and foamed injection molded article and compared to an article comprising the same amount of a polypropylene which has been polymerized in the presence of a Ziegler-Natta catalyst.

  • Polypropylene composition with excellent surface appearance
    Patent number: 11332603
    Abstract: The present invention is directed to a polypropylene composition (C) comprising a heterophasic propylene copolymer (HECO1) having an intrinsic viscosity (IV) of the xylene soluble fraction (XCS) above 3.5 dl/g, an inorganic filler (F) and a nucleating agent (NU) being a dicarboxylic acid and/or a salt thereof. Further, the present invention is directed to the use of said polypropylene composition (C) for the production of a foamed article as well as a foamed article comprising said polypropylene composition (C). The present invention is also directed to the use of a nucleating agent (NU) being dicarboxylic acid and/or a salt thereof for the reduction of tigerskin of a polypropylene composition.
