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 mixtu re 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 inorgan ic oxides or salts.
