    Abstract: 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.

    Abstract translation: 无卤阻燃热塑性弹性体组合物,其包括在每个嵌段中具有相对高的苯乙烯或单烯基芳烃含量的苯乙烯或单烯基芳烃的氢化苯乙烯嵌段共聚物。 令人惊奇的是,组合物含有少量或不含增塑软化剂。 组合物包括包含含有液态磷的组分和固体二级组分的非卤素阻燃剂的混合物。 组合物适用于挤出或模塑,并且可用于膜或电线和电缆应用。
