GOYENCHEM-DOPO GYC Phosphorus group flame retardant

GOYENCHEM-DOPO CAS NO. 35948-25-5 flame retardant

Intro

GO YEN CHEMICAL INDUSTRIAL CO.,LTD.(GYC Group) as a largest flame retardant, functional additive and fine chemical manufacturer in Asia that accomplished with strong R & D team and comprehensive product line.  We stand on the side of customers, solve problems positively and raise the core value of product.  That is the reason why we can receive trust from customers as the reliable supplier and earn good reputation from our business partner worldwide.  

 

GOYENCHEM-DOPO is an new designed phosphorus halogen-free flame retardant which is mainly applied on epoxy resin for PCB, and various of thermosetting resin.  Besides, GOYENCHEM-DOPO can be widely used in PCB circuit plates, electrical laminates, electronic equipment plastic, copper-lined laminate., etc. 

By using GOYENCHEM-DOPO, products can reach UL94-VO flame retardant standard with 2% phosphorus content in epoxy resin.  GOYENCHEM-DOPO can be easily solute in methanol, ethanol, isopropanol, chloroform, DMF,DMSO. 

It can easily absorb moisture in the open air and can be restored by heating without affecting the original properties. 

Comparing with tetrabromo bisphenol A (TBBA), the KFR-DOPO and pendant phosphorus group form better and stronger structure that provide better environment of flame retardancy, higher glass transition temperature, thermal stability and even the effect of low smoke.
