OPTIMUM ADDITIVE LEVEL OF ORGANOPHOSPHATE FLAME RETARDANTS IN MATERIALS

Flame retardants have been used in polymers to reduce the flammability of plastics, building materials,fabric and papers. In recent years, organophosphate flame retardants were used as substitutes forBrominated Flame Retardants. The consume amounts of organophosphate flame retardants in 2001was about 5 times than that of 2000 in Japan. Recently, several studies have shown the carcinogenicityand neurotoxicity of organophosphate flame retardants. Reducing the risk of fire is the main advantageof using organophosphate flame retardants.
