Flame-retardants for polystyrene and their performance

The flame retardant system and the nano synergistic flame retardant system for polystyrene (PS) were reviewed.The retarding performance and mechanism of the nano-clay,cage silsequioxane (POSS) and layered double hydroxides (LDHs) in polystyrene were discussed emphatically.The problems in the application of nano flame retardants and the idea of applied research in the future were proposed.
