Zusammenfassung:	Halogen-free, flame retardant compositions comprising in weight percent based on the weight of the composition: A. 20 to 60% TPU/Si-g-EVA polymer blend in which the Si-g-EVA is crosslinked, B. 1 to 25% organic phosphate ester, C. 30 to 60% metal hydrate, and D. 0.1 to 10% epoxidized novolac. Optionally, the compositions further comprise in weight percent based on the weight of the composition, one or more of: E. 0.01 to 0.5% anti-dripping agent, F. 0.1 to 2% additive; and G. 0.1 to 5% filler. L'invention concerne des compositions retardatrices de flamme, exempte d'halogène, comprenant, en pour cent en poids sur la base du poids de la composition : A. 20 à 60 % de mélange polymère TPU/Si-g-EVA dans lequel le Si-g-EVA est réticulé, B. 1 à 25 % d'ester phosphate organique, C. 30 à 60 % d'hydrate métallique, et D. 0,1 à 10 % de novolaque époxydée. Facultativement, les compositions comprennent en outre en pour cent en poids sur la base du poids de la composition, un ou plusieurs parmi : E. 0,01 à 0,5 % d'agent anti-égoutture, F. 0,1 à 2 % d'additif, et G. 0,1 à 5 % de charge.
