What is 10-(2,5-Dihydroxyphenyl)-10H-9-oxa-10-phospha-phenantbrene-10-oxide CAS 99208-50-1?

DOPO-HQ is a substitute for halogen-based flame retardants. Usually, DOPO-HQ and TDI are used as raw materials. By adjusting the ratio of the two, an addition reaction can be carried out to prepare a macromolecular reactive flame retardant containing terminal isocyanate groups. This flame retardant can be used for flame retardancy of materials such as thermoplastic polyurethane.

Specification

Appearance	White powder
Content	≥99.0%

Application

Introducing it as a flame-retardant co-curing agent into epoxy resin can increase the initial decomposition temperature of epoxy resin, it has excellent high-temperature carbonization property, the limiting oxygen index (LOI) value can be enhanced, it can pass the UL-94 V-0 grade, and at the same time, it can also improve the mechanical properties such as tensile strength of the material. Achieve a coordinated improvement in flame retardant function, mechanical properties and dynamic performan
