Halogen free flame retardant DOPO-HQ for copper clad laminate (CCL)

10-(2,5-Dihydroxyphenyl)-10H-9-oxa-10-phosphaphenanthrene-10-oxide

DOPO-HQ （CAS NO: 99208-50-1）is one derivative of DOPO, in January, 2018, the INTEL hold a meeting named “Intel Halogen free symposium ” in America, in the meeting a lots of electronical manufacturer promised they will use halogen free flame retardant to instead of halogen flame retardant..

DOPO-HQ is the most excellent flame retardant for producing copper clad laminate, epoxy resin.

Our DOPO-HQ have beening selling to Japan, Korea, Taiwan area.

If you have any interesting for DOPO-HQ, please do't hesitate to contact me

Halogen-free environmentally friendly flame retardant DOPO and derivative (DOPO-HQ/ HCA-HQ)

DOPO And derivative

9，10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOPO) is one of new type flame retardant agents, CAS NO：35948-25-5, It has bond of H-P, has active on alkenes, epoxy bonds and carbonyl groups, can react to produce many derivatives

Flame retardant DDP (2-(10-oxo-10H-9-oxa-10-phosphaphenanthren-10-ylmethyl) succinic acid

) is one  derivative DOPO, CAS NO: 63562-33-4, melting point is 193℃. it has a high thermal stability, oxidation resistance and excellent water resistance, reactive and additive flame retardant.

HCA-HQ (10-(2,5-Dihydroxyphenyl)-10H-9-oxa-10-phospha-phenantbrene-10-oxide

) is another one of derivative DOPO, CAS NO: 99208-50-1, Melting point is reach 250℃, it is a novel phosphorus reactive flame retardant, it is mainly used with epoxy

resin for high quality PCB, replacing the traditional bromine flame retardants, to meet the RoHS standards.

Flame retardant DDP and HCA-HQ all are Halogen-free, environmental protection flame retardantm, both have have  high thermal stability, oxidation resistance and excellent water resistance, now in Germany and France are one popular flame retardant agents.

If you have any inquiry or interest, please contact us soon, professional and competitive price will be sent.
