Abstract: the recent development in the halogen-free flame-retardants for ethylene-vinyl acetate copolymer ( EVA) was reviewed. }Che effect of different halogen-free flame retardants(like aluminium hydroxide, magnesium hydroxide, natural hydroxide and intumescent flame-retardants) and flame-retar-dant synergists (like red phosphorus and zinc borate) in the EVA composite were observed via limited oxygen index, UL-94,cone calorimeter and other performance indexes. the main EVA based fireproof materials were categorized according to their feature and flame-retardant mechanism. The future development of EVA flame-retardant composite was forecasted.

Key words: ethylene-vinyl acetate copolymer, halogen-free flame retardant, metal hydroxide, modifica-Lion, synergistic flame retardancy
