RDP

RDP is a high molecular weight phosphate ester flame retardant,which is used in engineering resins such as modified PPO,polycarbonate/styrenic blend. Chemical name TETRAPHENYL M-PHENYLENE BIS(PHOSPHATE) Equivalent name Tetraphenyl resorcinol bis(diphenyl phosphate) Commercial brand ROYAL RDP CAS No. 57583-54-7 Molecular formula C30H24O8P2 Structural formula Technical specification Items Standard Appearance Clear liquid Density (d20) 1.31 Viscosity (25℃, cp) 390-790 Phosphorus content (wt. %) 10.5% Tpp content (wt. %) 5.0 max Free phenol(ppm) 500 max Acid value (mg koh/g) 0.1 max Applications RDP is a halogen-free phosphate ester flame retardant used in engineered resins, whose superiority is demonstrated in low volatility and high heat stability that that can tolerate high temperature processing required of many engineered resins. It can be recommended as flame retardant for PC/ABS, PPO/HIPS Package 230kg/Zinked iron drum; 1200kg/IBC drum; 20-25tons/ISOTANK
