RDP flame retardant (CAS 57583-54-7) is halogen-free aryl phosphate ester, resorcinol bis(diphenyl phosphate). This transparent flame retardant is developed for clear polycarbonate and transparent PC/ABS optical components. It features outstanding compatibility with clear resin matrix, hardly causing haze or yellowing after molding. It provides reliable flame suppression while keeping original optical properties, widely used for transparent optical plastic parts in electronics and optical indust
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 Advantage: High transparency for clear PC and PC/ABS optical parts
Key Performance & TDSThis transparent RDP flame retardant has great miscibility with clear PC and transparent PC/ABS blends. It preserves high light transmittance and low haze of molded optical parts, no obvious color shift under proper processing conditions. It owns good thermal stability and low volatility, reducing gas marks and surface defects during high-temperature molding of transparent plastics. High phosphorus content brings efficient flame retardancy, helping clear PC and PC/ABS products achieve target UL94 flame rating. Halogen-free structure releases low smoke in combustion, and has minimal negative influence on mechanical performance of transparent optical components.
