Chemical name: bisphenol A-bis (diphenyl phosphate)
English abbreviation: BDP
Molecular formula: C39H34O8P2
Molecular weight: 692.63
CAS No. 5945-33-5
BDP is a halogen-free flame retardant belonging to low-polyphosphate. It is based on bisphenol A and bisphosphate as monomers.
BDP is a halogen-free phosphate flame retardant with low volatility, excellent hydrolysis stability and thermal stability. It can be used as flame retardant plasticizer for PC/ABS and PPO/HIPS engineering plastics. It can also be used as flame retardant plasticizer of PVC with high thermal stability.
