    Abstract   The current progress in research of some non-halogen flame retardants, such as phosphorous flame retardant, silicon flame retardant and nitrogenous flame retardant, intumescent flame retardant and nanosized flame retardant are reviewed, with emphasis on the intumescent flame retardant composed of APP mostly．The intumescent flame retardant composed of APP is the excellent typical representation of the non-halogen flame retardant．It has so many excellences，such as good stability，high efficiency，suppressing smog，safety，nontoxicity and environment-friendly property, thus gets extensive application which will take the place of the halogen flame retardant gradually.
