Synergistic Effects of Fe2O3 with Layered Double Hydroxides in EVA/LDH Composites

The synergistic effects of Fe2O3 with layered double hydroxides (LDH) in ethylene vinyl acetate copolymer/LDH (EVA/LDH) composites have been studied using limiting oxygen index (LOI), UL-94 tests, and cone calorimeter test (CCT). The results from the LOI and UL-94 tests show that the Fe2O3 can also act as flame retardant synergistic agents in the EVA/LDH composites. The CCT data indicated that the addition of Fe2O3 in the EVA/LDH system can greatly reduce the heat release rate, total heat release, carbon monoxide and carbon dioxide.
