The flammability properties of three series of Ethylene-Vinyl Acetate/Magnesium Hydroxide/Layered Double Hydroxide(EVA/MH/LDH) composites as well as the flame retardance effect between LDH and the conventional flame retardant additive MH are investigated.In addition to acting as an insulating barrier,LDH assists the dispersion of MH particles in the EVA matrix,and promotes the formation of the char residues because of its abundant interlayer hydroxyl groups.Composites containing LDH show good flame retardancy in Cone and LOI testings.This means that the combustion properties of the composites have decreased,which may lessen the fire hazard when this materials are used.
