Flame Retardant DOPO - Hunan Chemical BV
CAS number 35948-25-5. Flame Retardant DOPO. Product name: DOPO Product Form: Solid Chemical name: 9,10-Dihydro-9-oxa-10-phosphaphenanthrene-10-oxide
An overview of some recent advances in DOPO-derivatives
These DOPO-derivatives are used as flame retardants mainly in epoxy resins [3], [5], [11], [12], [13], [15], for applications in adhesives, composites, printed wiring boards and others [17]. As some halogenated flame retardants have been found to be toxic, the research on halogen-free flame retardants is gaining more and more importance [18].
Flame Retardants - National Institute of Environmental Health
Flame retardants are chemicals that are applied to materials to prevent the start or slow the growth of fire. They have been used in many consumer and industrial products since the 1970s, to decrease the ability of materials to ignite. Flame retardants are often added or applied to the following products. Furnishings, such as foam, upholstery
Properties and flame retardant mechanism of sulfuretted DOPO
Properties and flame retardant mechanism of sulfuretted DOPO derivative in epoxy resin [J]. Acta Materiae Compositae Sinica, 2025, 39 (10): 4518-4530. doi: 10.13801/j.cnki.fhclxb.20251228.001...
- What is Dopo flame retardant?
- 0.3 max. DOPO is a kind of reactive, halogen free flame retardant additive with excellent heat stability and oxidation resistance. As phosphorous organic its performance are chemically linked to resin matrix and is better than other phosphate esters in flame retarding due to the P-C bond.

- What are reactive Dopo based flame retardants for epoxy resins?
- This review focuses on recent advances in reactive DOPO–based flame retardants for epoxy resins, including reactive monomers, curing agents and hybrid structures. There are also highlighted fire retardant mechanisms of the DOPO derivatives and thermal and mechanical features of the epoxy systems.
- How does Dopo exhibit a flame retardant mechanism?
- DOPO exhibits mainly gas phase flame retardant mechanism through the release of free radical scavangers generated during material combustion. It may also exhibit condensed phase by dehydration to form carbonaceous protective layers .
- Can Amine hardeners be used as flame retadants for epoxy resins?
- A series of DOPO–based amine hardeners were also used as flame retadants for epoxy resins. However, a high content of aromatic moieties significantly decreased their solubility in the epoxy resins, hence greatly limiting their use in composites [12, 13].
- Are halogen based flame retardants safe?
- Numerous halogen–based flame retardants, such as polybrominated diphenyl ethers, which were previously used in epoxy resins, have been prohibited worldwide due to serious environmental implications.
