RDP flame retardant (CAS 57583-54-7) is halogen-free aryl phosphate ester, also known as resorcinol bis(diphenyl phosphate). It is a liquid phosphorus-based flame retardant designed for engineering plastic modification. It has excellent compatibility with PC, PC/ABS and PPO resin systems, providing efficient flame suppression while retaining the mechanical properties of polymer substrates. It is a mainstream halogen-free flame retardant adopted by plastic compounders for high-performance enginee

Product Detail

Product DetailsChemical IdentityProduct Name: Resorcinol Bis(diphenyl phosphate), RDP CAS No.: 57583-54-7 Chemical Type: Halogen-free aryl phosphate ester Physical Form: Transparent viscous liquid Core Function: Flame retardant modifier for PC, PC/ABS, PPO engineering plastic

Key Performance & TDSRDP flame retardant features high phosphorus content for outstanding flame retardant efficiency. It possesses good thermal stability and low volatility, resisting decomposition during high-temperature extrusion and injection molding processes, reducing mold deposits and volatile emission. It shows great miscibility with polycarbonate, PC/ABS blends and PPO matrix. With proper addition dosage, it can help engineering plastics achieve UL94 V-0 rating. Halogen-free structure ensures low smoke and non-corrosive gas generation under combustion, with limited negative influence on impact strength and surface quality of finished plastic parts.

Applications

Flame retardant modification of PC polycarbonate resin
PC/ABS alloy compounding for electrical components
PPO modified engineering plastic production
