T he application of IFR and its syner istic a ents in polymer materials w as introduced. Four cate ories of syner istic a ents for IFR containin ammonium polyphosphate, such as zeolite, metal ox ide and metal salt, metal hydrox ide, and expanded raphite w ere introduced. The flame retardancy and the flame retardant mechanism w ere also discussed. It w as show n that the efficiency of the IFR could be remarkably improved by the addition of syner istic a ents, and the har m to the matrix and the loadin level w ere also decreased. The study on the syner istic a ents also pr omoted the study on surface modification and micro-encapsulation of APP . ey words: ammonium polyphosphate; intumescent flame retardant; syner istic a ent; flam
