Product Introduction
DOPO
1.Product description
This product is a phosphinate cyclic phosphate, a novel flame retardant intermediate with high thermal stability, antioxidant properties, and excellent water resistance. It is used as both a reactive and additive flame retardant, mainly in the fields of polyester fibers, polyurethane foam plastics, thermosetting resins, and adhesives.
2.Product Parameters
Chemical Name：9,10-Dihydro-9-oxa-10-phosphaphenanthrene 10-oxide
CAS：35948-25-5；
Molecular Formula：C12H9O2P；
Molecular Weight：216
3.Product Applications
①. Reactive flame retardant for epoxy resins. Through reaction with epichlorohydrin followed by hydroquinone, it serves as a sealing material for electrical insulation and semiconductor materials, ensuring electrical insulation, low volatility, and low pollution. It has good miscibility with resins like ABS, forming flame-retardant transparent plastics when added.
②. Coloration inhibitor. It prevents heat-induced coloration in ABS, AS, PP, PS, epoxy resins, phenolic resins, alkyd resins, and surfactants, as well as light and heat-induced coloration in polyurethanes.
③. Used in the production of a series of DOPO-derivative flame retardants for flame-retardant treatment of polymer materials such as PET, nylon, epoxy resins, polyurethanes, and unsaturated polyester resins.
4.Product Characteristics
①. Excellent thermal stability with high thermal decomposition temperature.
②. Low dosage, good dispersion, effective flame retardancy, and superior material quality.
③. Good color resistance.
④. Halogen-free and environmentally friendly, compliant with EU ROHS directives.
⑤. Solubility: Easily soluble in methanol,ethanol,chloroform, dimethylformamide, and dioxane. Soluble in benzene, insoluble in water and hexane
