Description
Flame retardant DOPO-HQ, also konwn as 10- (2,5-Dihydroxyphenyl) -10H-9-oxa-10-phospha-phenantbrene-10-oxide, soluble in organic solvents such as methanol, ethanol, toluene, and almost insoluble water. Flame retardant DOPO-HQ is a reactive halogen-free flame retardant and an alternative to halogen flame retardants. Flame retardant DOPO-HQ is mainly used to produce halogen-free flame retardant epoxy resin, can be used as a raw material for packaging of semiconductor materials, printed wiring boards, LED light-emitting tubes, can also be used for products that must meet RoHS requirements, used in the production of intermediates for the synthesis of reactive flame retardants. The flame retardant epoxy resin synthesized with it has better flame retardancy and thermal stability. The use of 10- (2,5-Dihydroxyphenyl) -10H-9-oxa-10-phospha-phenantbrene-10-oxide avoids environmental pollution caused by brominated epoxy resins during use and recycling. It does not affect other properties of polyester while improving flame retardancy and thermal stability, and avoids the disadvantages that general flame retardants are incompatible with polyester, easy to precipitate, and have a large impact on mechanical properties. 10- (2,5-Dihydroxyphenyl) -10H-9-oxa-10-phospha-phenantbrene-10-oxide is in line with the current trend of flame retardant smoke suppression and low toxicity, and is an environmentally friendly flame retardant.
