Because of low density and low thermal conductivity untreated FPUFs are relatively easy to ignite with evolution of smoke and toxic gases during combustion. Therefore it is essential to endow FPUF with good flame retardancy. However the use of halogen-based flame retardants is currently restricted because of potential toxicity and environmental problems. Hence more attention has been paid recently to developing halogen-free flame retardant FPUF. The research progress of halogen-free flame retardant including additive halogen-free flame retardants reactive halogen-free flame retardants and layer-by-layer assembled flame resistant coatings used in FPUF in recent years was summarized. Developing high molecular weight multi-element organic additive flame retardant and intumescent flame retardant as well as composite flame retardant and resolving slow assembly problem for layer-by-layer assembled flame resistant coatings should be the development trend of the halogen-free flame-retardant techniques for FPUF.
