    Abstract: Disclosed is a filled polyolefin composition comprising a blend of a 20-50 wt.% of an heterophasic polypropylene (a), 10-25 wt.% of a propylene polymer (b) having MFR (ISO1133 230°C/2.16Kg) higher than 800 g/10 min., 5-35 wt.% of a propylene polymer (c) having MFR (ISO1133 230°C/2.16Kg) of 0.5-20 and a tensile modulus (ISO 527-1,-2) equal to or greater that 1000 MPa, 5-35 wt.% of glass fibers (d) and 0-5 wt.% of a compatibilizer (e). The filled polyolefin composition has a high fluidity in the molten state, good balance of mechanical properties and improved thermal properties. The filled composition finds use in injection molding applications.

    IPC: C08L23/16

    Abstract: Disclosed is a filled polyolefin composition comprising a blend of a 30-70wt.% of a first heterophasic polypropylene HECO1 and 70-30 wt.% of a second heterophasic polypropylene HECO2, the heterophasic copolymers differing in MFR and type of comonomers, in combination with glass fibers and optionally a compatibilizer. The filled polyolefin composition has a high fluidity in the molten state and a good balance of mechanical properties and finds use in injection molding applications.

    IPC: C08L23/14

    Abstract: Heterophasic copolymers of propylene with a MFR2 (230°C/2.16 Kg) of from 3.0 to 12.0 g/10 min comprise: (a) from 55 to 75 wt. % of a component (A) being a copolymer of propylene with ethylene or a C4-C10 alpha-olefin, comprising from 0.5 to 2.0 wt. % of ethylene and/or C4-C10 alpha-olefin units and having a MFR2 (230°C/2.16 K g) ranging from 60 to 140 g/10 min; and (b) from 25 to 45 wt. % of a component (B) being a propylene-ethylene copolymer comprising 25 to 45 wt. % of ethylene units and having a value of the intrinsic viscosity of the fraction soluble in xylene at room temperature (XS-IV) ranging from 5 to 9 dl/g.
