RDP flame retardant (CAS 57583-54-7) is halogen-free aryl phosphate ester, equivalent to CR-733S. It is customized for thin-wall PC and PC/ABS molded components. It maintains high flame retardant efficiency even in thin-wall sections, and exhibits excellent thermal stability and low volatility during high-speed injection molding. It serves as cost-effective replacement of CR-733S for plastic compounders producing thin-wall electrical plastic parts.

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 Advantage: CR-733S equivalent, suitable for thin-wall PC & PC/ABS

Key Performance & TDSThis RDP flame retardant matches the performance benchmark of CR-733S. It keeps reliable flame inhibition on thin-wall PC and PC/ABS articles, which is difficult for many flame retardants to achieve. It has low volatility and good heat resistance, reducing gas marks and mold deposit in thin-wall high-speed injection molding. Good compatibility with PC and PC/ABS matrix, less adverse impact on impact strength and surface finish of thin molded parts. Halogen-free structure releases low smoke and non-corrosive gas upon combustion. It can help thin-wall PC/ABS products achieve UL94 V-0 rating at recommended loading.

Applications

Thin-wall PC and PC/ABS injection molded components
Miniature electrical housings and thin-wall connectors
Precision thin-section electronic plastic parts
PC/ABS alloy compounding replacing CR-733S
Thin-wall engineering plastic requiring halogen-free flame retardancy

ComplianceThis product complies with RoHS and REACH regulations, suitable for export thin-wall electronic plastic projects.

Why Choose JSYWe supply factory direct RDP flame retardant as CR-733S equivalent. Stable batch quality, consistent thin-wall flame performance, flexible MOQ and professional formulation support for thin-wall PC/ABS modification.
