The latest development of non-halogen flame-retarded PA has been reviewed. The flame-retarded PA described in this paper includes those treated with melamine derivatives (such as MC and MPP ) and reactive phosphorous compounds. In addition, the PA/inorganics nanocomposite is also involved. The present situation and flame retardant mechanism of the non-halogen flame-retarded PA mentioned above were discussed. The developmental trends and the research work which focuss our minds on the field of non-halogen flame-retarded PA in the future were predicted and proposed by the author.
