Abstract: The invention relates to a heterophasic polypropylene compositions comprising 78- 85 % by weight of a propylene homopolymer or copolymer matrix with up to 2.0 % by weight of ethylene units, 15-22 % by weight of an elastomeric ethylene-propylene copolymer and a clarifying agent. The composition has an intrinsic viscosity of the xylene soluble fraction at room temperature of from 0.5 to 1.5 dl/g and a melt flow rate (230°C, 2.16 kg) of 0.5 to 10 g/10 min. The compositions of the present invention can be used to prepare sheets for thermoforming applications.

Abstract: Provided is a polypropylene composition having an excellent balance between stiffness and low temperature impact resistance as well as having high flowability and gloss. A polypropylene composition comprising: as component (1), a propylene (co)polymer containing 0 to 0.5% by weight of an ethylene-derived unit; as component (2), an ethylene/propylene copolymer containing 15 to 30% by weight of an ethylene-derived unit; and 0.01 to 1.0 parts by weight of a crystal nucleating agent based on a total of 100 parts by weight of component (1) and component (2); wherein the polypropylene composition satisfies the following requirements: 1) the Mw/Mn value of xylene insolubles (XI) of the composition as measured by GPC is in the range of 6 to 20, 2) the weight ratio of component (1) to component (2) is in the range of 82:18 to 90:10, 3) the intrinsic viscosity of xylene solubles (XSIV) of the composition is in the range of 2.5 to 3.4 dl/g, 4) the MFR (at 230°C under a load of 2.16 kg) of the composition is in the range of 3 to 10 g/10 min.
