A review of non-halogenated flame retardant
Sanjay D Jadhav
Recent patent and literature indicate a growing interest in non-halogenated flame retardants are on the fast growing track due to the environmental consideration, although sometimes efficiency, lower density & good light stability are the significant factors. Patent published on the flame retardancy of polycarbonate & its blends significantly exceed the number of patent on the flame retardancy of any other polymer. Bridged aromatic phosphates have found broad applications because of there good thermal stability, high efficiency & low volatility. Flame retardant has very important role to play in today’s science and technological field and considering the importance various researcher have studied various aspect and application areas for the same. Similarly various innovative molecules have been invented and tried various researchers but this is not the end of the research. This review summarizes main advances published over the period of last 20 years, outlining the work carried out on synthesis of non-halogenated flame retardant compounds and application of it. Another actively reported group of compounds are the metal salt of phosphorous compounds which have been found to be particularly effective in poly butylene terepthalate & polycarbonate. These products are synergistic with a number of phosphorous & nitrogen containing compounds which seems to be a very efficient and commercially useful in nylon
