DOPO-HQ

Catalog	ACM99208501-1
CAS	99208-50-1
Structure
Description	DOPO-HQ is a newly-designed,non-halogenated flame retardant. Due to the rigidbiphenyl,the phosphorus moiety，and the reactive phenol group,DOPO-HQ cancrosslink with epoxy resins to enhance the fire-resistancy, thermal stability, and solvent-resistancy of polymers. Furthermore, DOPO-HQ is environmentally friendly since itdoes not emit toxic hydrochloric or hydrobromic gas under flame.
