  • Patent number: 7125924
    Abstract: Polyolefin compositions filled with high amounts of inorganic fillers comprising, by weight: (I) 20 to 60% by weight of an heterophasic polyolefin composition comprising: A) from 8 to 25% by weight of a crystalline polymer fraction selected from propylene homopolymer, propylene copolymers and mixture there; and B) from 75 to 92% by weight of an elastomeric fraction comprising at least an elastomeric copolymer of propylene or ethylene with 15 to 45% of at least one alpha-olefin, having solubility in xylene at room temperature greater than 50% by weight, the intrinsic viscosity of the xylene soluble fraction ranging from 3.0 to 6.5 dl/g; and (II) 40 to 80% by weight of an inorganic filler selected from flame-retardant inorganic fillers and inorganic oxides or salts.

  • Patent number: 6723792
    Abstract: A dispersion of one or more additives to be used in the processing of olefin polymers or copolymers, said dispersion comprising nonextruded particles of olefin polymers containing at least two immiscible polyolefinic phases and having internal voids partially or totally filled by the said additive or additives.

  • Patent number: 6673855
    Abstract: The invention concerns polyolefin compositions with high flame resistance. The compositions comprise (percent by weight): A) from 20 to 60% by weight of a heterophasic olefin polymer composition comprising a crystalline olefin polymer (a) and an elastomeric olefin polymer (b), said composition (A) being optionally modified with at least one functional monomer in an amount from 0.005% to 0.6% by weight with respect to the total weight of the total composition; B) from 15 to 40% by weight of one or more than one inorganic hydrated fillers; C) from 12 to 40% by weight of one or more than one organic flame retardants containing nitrogen in the molecule; D) from 0 to 40% by weight of one or more than one inorganic anhydrous fillers. Possible applications include the use as insulating material in electric wires and cables and the use as waterproofing sheets for roofs and tunnels.
