Product Introduction: DOPO-HO, as a derivative of DOPO, can also be used for flame retardant treatment of various polymer materials such as linear polyester, polyamide, epoxy resin, polyurethane, as well as plastics, steel lining laminates, circuit boards, and other materials used in electronic devices. DOPO reacts with epichlorohydrin and then with hydroquinone, especially when epoxy resin is used as an electrical insulation material and a sealing material for semiconductor materials. It requires electrical insulation, low volatility, and low pollution, ABS， All have good compatibility and form flame-retardant transparent plastic after addition. Chemical name: 10- (2,5-dihydroxy) -10-hydro-9-oxa-10-phosphaphenanthrene-10-oxide, other names: (HCA, trade name of Mitsukoshi Corporation, Japan), abbreviated as DOPO-HQ, alias: HQ, ODOPB, DOPO-BQ, CAS No.: 99208-50-1, molecular formula: C18H1304 P. It is a new type of phosphorus containing environmentally friendly halogen-free flame retardant, mainly used in high-end epoxy resins such as circuit boards, and can replace bromine containing flame retardants (tetrabromobisphenol A). It can be used for semiconductor material packaging, printed circuit boards, LED light-emitting tubes, etc. Used for products that must comply with ROHS requirements, intermediates for synthesizing reactive flame retardants, etc. Quality indicators Appearance: White powder Molecular weight: 324 Purity: 99% Melting point: 247-253C Moisture: 0.2% Hydroxyl value: 162 Phosphorus content: 9.6% Solubility: THF, ethylene glycol, DMF， Methanol, ethanol, and ether solvents. Packaging 20kg/pack. TEL: 020-82180286FAX: 020-8201293ADD: F910, No. 10 Guanhong Road, Huangpu District, Guangzhou http://ww.ebsuax.c
