Resorcinol bis(diphenyl phosphate), a non-halogen flame-retardant additive

This paper is a review of Resorcinol bis(diphenyl phosphate) (RDP), a non-halogen aromatic oligomeric phosphate flame-retardant and flow modifier. Its high thermal stability and low volatility when compared to the triaryl phosphates makes it ideal for use in applications where high processing temperatures are required. Thermogravimetric data showing the effects of RDP on modified PPO and Plycarbonate ABS blends are presented. Current and potential end uses in thermoplastic resins and polyurethanes are discussed.
