RDP Flame Retardant for Polycarbonate CAS 57583-54-7, Resorcinol Bis(diphenyl phosphate) High Thermal Stability Low Volatility
RDP flame retardant (CAS 57583-54-7) is halogen-free aryl phosphate ester, named resorcinol bis(diphenyl phosphate). It is specially developed for polycarbonate modification. With high thermal stability and low volatility, it will not easily decompose or evaporate under high-temperature PC processing. It provides efficient flame retardancy while preserving polycarbonate’s mechanical performance and optical property, widely used in PC compounding for electrical and industrial plastic parts.
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 Feature: High thermal stability and low volatility for polycarbonate
Key Performance & TDSThis RDP flame retardant exhibits excellent thermal stability, resisting thermal degradation during high temperature extrusion and injection molding of polycarbonate. Low volatility effectively reduces mold fouling, volatile gas and surface defects of molded PC products. Its high phosphorus content delivers efficient flame inhibition, helping polycarbonate reach UL94 V-0 rating at recommended loading. It has great compatibility with PC matrix, minimizing negative impact on impact strength, tensile property and transparency of polycarbonate parts. Halogen-free formula generates low smoke and non-corrosive gas when burning.
Applications
- Flame retardant modification of pure polycarbonate resin
- High-temperature processed PC molded components
- Transparent polycarbonate sheets and covers
- Electrical protective housings made from PC
- Polycarbonate products requiring low volatile flame retardant
ComplianceThis product complies with RoHS and REACH regulations, applicable for export polycarbonate plastic projects.
