Flame retardant thermoplastic polyurethane (TPU) compositions are disclosed having a flame retardant package comprising an organo-phosphinate component, an organo-phosphate component, and a polyhydric alcohol. The flame retardant components may be present in an amount from about 5 to about 40 weight percent of the phosphinate compound; from about 5 to about 20 weight percent of the phosphate compound, and from about 0.1 to about 15 weight percent of the polyhydric alcohol, based on the total weight of the TPU composition. Processes are disclosed to make the TPU compositions and to make wire and cable constructions employing the TPU compositions as the jacket of the wire and cable constructions. The TPU compositions exhibit excellent flame retardant capabilities as measured by Limited Oxygen Index testing and/or UL 94 Vertical Burn tests.

L'invention concerne des compositions à base de polyuréthanne thermoplastique retardateur de flamme non halogène (TPU) comprenant un ensemble retardateur de flamme qui contient un composant d'organophosphinate, un composant d'organophosphate et un alcool polyhydrique. Lesdits composants retardateur de flamme peuvent être présents selon une quantité comprise entre environ 5 à 40 % en poids du composé de phosphinate, environ 5 à 20 % en poids du composant de phosphate et environ 0,1 à 15 % en poids de l'alcool polyhydrique sur la base du poids total de la composition TPU. L'invention concerne également des procédés permettant de produire ces compositions ainsi que des constructions de fils et de câbles dans lesquelles ces compositions sont utilisées pour le gainage desdites constructions de fils et de câbles. Les compositions TPU présentent d'excellentes propriétés retardatrices de flamme, telles que mesurées par des tests d'indice d'oxygène et/ou des tests de combustion verticale selon UL 94.
