DOPO Flame Retardant JSYA-DOPO CAS 35948-25-5, Reactive Halogen-Free Phosphorus for Epoxy CCL PCB
DOPO Flame Retardant JSYA-DOPO is high purity 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide with CAS 35948-25-5, supplied as white fine powder. It belongs to reactive halogen-free organophosphorus flame retardant widely used in epoxy copper clad laminate (CCL) and PCB substrate industry.
Different from additive-type flame retardants, JSYA-DOPO features active P-H bond. It can react with epoxy groups and be chemically incorporated into epoxy resin crosslinking network during curing. The p
Chemical Identity / TDSProduct Name: DOPO Flame Retardant JSYA-DOPO CAS No.: 35948-25-5 Chemical Name: 9,10-Dihydro-9-oxa-10-phosphaphenanthrene-10-oxide Synonyms: DOPO, DOPO monomer Physical Form: White fine powder Core Benefit: Reactive halogen-free phosphorus flame retardant chemically grafted into epoxy network for CCL and PCB substrates
