RDP Flame Retardant Liquid CAS 57583-54-7, Halogen-Free Aryl Phosphate Low Volatility for Engineering Plastic
RDP flame retardant liquid (CAS 57583-54-7) is halogen-free aryl phosphate ester, also known as resorcinol bis(diphenyl phosphate). As a liquid phosphorus flame retardant, it can be smoothly fed and evenly dispersed in engineering plastic matrix in twin-screw compounding lines. It features low volatility and excellent thermal stability, delivering effective flame inhibition without severely damaging mechanical properties of modified engineering plastics. It is widely applied in PC, PC/ABS, PPO a
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: Liquid form, low volatility for engineering plastic modification
Key Performance & TDSThis liquid RDP flame retardant is convenient for continuous liquid feeding in plastic compounding production, achieving homogeneous distribution inside polymer blends. Low volatility greatly reduces volatile emission and mold deposit under high processing temperature, avoiding gas streaks and product discoloration. It has high phosphorus content to realize efficient flame suppression, enabling finished engineering plastics to reach UL94 V-0 at recommended dosage. Halogen-free structure generates low smoke and non-corrosive gas during burning. It maintains balanced impact strength and surface quality of molded plastic articles.
Applications
- PC, PC/ABS, PPO engineering plastic alloy modification
- Plastic compounding lines with liquid feeding system
- Electrical and electronic engineering plastic components
- High temperature molded plastic parts requiring halogen-free flame retardant
- Modified plastics needing consistent flame retardant dispersion
ComplianceThis product meets RoHS and REACH requirements, suitable for global export engineering plastic modification projects.
