Flame retardant nanocomposites are synthesized by melt-blending ethylene-vinyl acetate copolymers with modified layered silicates as nanofillers. Thermogravimetric analysis performed under air demonstrates a clear increase in the thermal stability of the layered silicate-based nanocomposites. A cone calorimeter was used to investigate fire hazards. The nanocomposites cause a large decrease in heat release. The char formation is the main important factor for the improvement and its function is outlined. Further improvements of the flame retardancy by combinations of nanofillers and traditional FR-additives on basis metal hydroxides are also studied. The nanocomposites bases on nanofillers and ATH can be used as very efficient systems for flame retardant cables. The corresponding results are outlined for a coaxial cable fulfilling the UL 1666 riser test.
