Highly filled polyolefin compositions with improved balance of properties particularly for applications where puncture and tear resistance is requested comprising a flexible heterophasic polyolefin composition (I), consisting of a crystalline polymer fraction (A) consisting of a copolymer of propylene with ethylene having a fraction insoluble in xylene at 25DEG C of at least 90% by weight, and an elastomeric fraction (B) consisting of a copolymer or blend of copolymers of ethylene with propylene; said copolymer or blend containing units derived from ethylene in a quantity lower than 40% by weight. The fraction soluble in xylene at 25 DEG C of said polyolefin composition having IVgpc lower than 2.5 dl/g, and a broad molecular weight distribution Mw/Mn (GPC) equal to or higher than 4, Mz/Mw (GPC) equal to or higher than 2.5.The filled polyolefin composition is further comprising of an inorganic filler (II) and a butene-1 copolymer having: flexural modulus (ISO 178) lower than 60 MPa, Shore A (ISO 868) lower than 90 and Tg (DMTA) lower than -20 DEG C.
