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: A composition contains at least a copolyamide (PA-1) as a component (I), produced by polymerization of at least one lactam and of a monomer mixture (M) which contains at least a C32-C40 dimer acid and at least a C4-C12 diamine; and a flame retardant (F1) as a component (II). The flame retardant (F1) is selected from melamine cyanurates, magnesium hydroxide, and phosphorus-containing flame retardants. A process can be used for preparing such compositions, and the composition can be used for producing shaped articles.

Abstract: A composition contains at least a thermoplastic polyurethane (TPU-1) and a copolyamide (PA-1), prepared by polymerization of at least one lactam and of a monomer mixture (M). The monomer mixture (M) contains at least a C32-C40 dimer acid as a component (B1), and at least a C4-C12 diamine as a component (B2). A process can be used for preparing such compositions, and the composition can be used for producing shaped articles.
