Abstract: A composition contains a thermoplastic polyurethane, a first flame retardant (F1) selected from ammonium phosphate and ammonium polyphosphates, and a phosphorus-containing flame retardant (F2) selected from derivatives of phosphinic acid, derivatives of phosphonic acid, and derivatives of phosphoric acid. The composition according to the present invention is useful for the production of cable sheathings.

Abstract: A composition contains thermoplastic polyurethane, which is the reaction product of a pentamethylene diisocyanate, a polycarbonate diol, and a chain extender. The composition is useful for producing articles. A production process for producing a filled composition involves adding glass to the composition. Articles can be derived from the composition and the filled composition.

Abstract: Foamed pellets contain a thermoplastic polyurethane obtainable or obtained by reacting a polyisocyanate composition (IC), containing at least one aliphatic diisocyanate having a number-average molecular weight of less than 200 g/mol, at least one chain extender (CE1), and a polyol composition (PC). A process can be used for the production of such foamed pellets. The foamed pellets can be used for the production of a molded body.
