Zusammenfassung:	Halogen free flame retardant thermoplastic elastomer compositions including a hydrogenated styrenic block copolymer having relatively high styrene or mono alkenyl arene content and styrene or mono alkenyl arene in each block. Surprisingly, the compositions contain low amounts or are free of plasticizing softeners. The compositions include a blend of non-halogen flame retardants including a liquid phosphorous-containing component and a solid secondary component. The compositions are suitable for extrusion or molding and are useful for films or wire and cable applications. L'invention concerne des compositions d'élastomère thermoplastique ignifuge sans halogénés comprenant un copolymère séquencé styrénique hydrogéné ayant une teneur relativement élevée en styrène ou arène mono-alcényle et du styrène ou de l'arène mono-alcényle dans chaque bloc. Étonnamment, les compositions contiennent des quantités faibles ou sont exemptes d'assouplissants de plastification. Les compositions contiennent un mélange d'agents ignifuges non halogénés incluant un composant contenant du phosphore liquide et un composant secondaire solide. Les compositions sont adaptées à l'extrusion ou au moulage et sont utiles pour des films ou des applications de fils et de câbles.
