Product introduction

DOPO-HQ, as a derivative of DOPO, can also be applied to many kinds of polymer 

materials, such as linear polyester, polyamide, epoxy resin, polyurethane and other 

electronic materials, such as plastic, copper lining, pressing layer, circuit board and so on.

The reaction of DOPO with epichlorohydrin and then reacted with hydroquinone,

 especially epoxy resin as electrical insulating materials, semiconductor materials used 

in sealing material, requirements for electrical insulation, low volatility, low pollution,

 ABS, have good compatibility, add after the formation of transparent plastic flame retardant.

Chemical name: 10- (2,5- * -10- two hydroxy hydrogen) -9- oxa phosphaphenanthrene

 -10- -10- oxide, the other (Japanese Name: three company name HCA), referred to as:

 DOPO-HQ, HQ, ODOPB, alias: DOPO-BQ, CAS, No.:99208-50-1,

It is a new type phosphorus containing environmental friendly halogen free flame retardant.

 It is mainly used for high-grade epoxy resin such as printed circuit boards. It can replace

 bromine flame retardants (four bromine bisphenol -A), which can be used for packaging 

semiconductor materials, printed circuit boards, LED light-emitting tubes, etc. For the 

products that must meet the requirements of ROHS, it is used to synthesize the intermediate

 of the reactive flame retardant.
