The synergistic effects of titanium dioxide (TiO 2 ) with layered double hydroxides (LDH) in ethylene vinyl acetate copolymer/LDH (EVA/LDH) composites have been studied using thermogravimetric analysis (TGA), limiting oxygen index (LOI), UL‐94 tests, and cone calorimeter test (CCT). The results from the UL‐94 test show that the TiO 2 can also act as flame retardant synergistic agents in the EVA/LDH composites. The CCT data indicated that the addition of TiO 2 in EVA/LDH system can greatly reduce the heat release rate and the production rate of carbon monoxide. The TGA data show that the TiO 2 as excellent flameretardant synergist of LDH can increase the thermal stability of the flame retardant composites at high temperature, indicating the effect of condensed phase mechanism is the main reason of the improvement of flame retardancy.
