Chemical name: resorcinol bis (diphenyl phosphate)
English abbreviation: RDP
Molecular formula: C30H24O8P2
Molecular weight: 574.43
CAS No. 57583-54-7
RDP is a low-polymer halogen-free phosphorus flame retardant based on resorcinol bis (diphenyl phosphate) monomer.
RDP is a halogen-free phosphate flame retardant with low volatility and excellent thermal stability, which can meet the needs of engineering plastics processing. It can be used as flame retardant for engineering plastics such as PC/ABS and PPO/HIPS.
