<p>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.</p> |
