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

Abstract

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.

Keywords

synergistic effect layered double hydroxide halogen-free flame retardant.
