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 retardant-DOPO - ChemBK
Introduction. 9,10-dihydro -9-oxa -10-phosphazene -10-oxide is also called 9,10-dihydro -9-oxa -10-phosphazene -10-oxide (DOPO), which is an important new reactive phosphorus-containing flame retardant. The flame retardants synthesized by DOPO and its derivatives have the characteristics of high efficiency, halogen-free, smokeless, non-toxic

- 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.
- Who is Hunan chemical BV?
- We are Hunan Chemical BV and dedicated to the chemical industry. We supply additives to plastic and rubber industry and coating industry. We also supply intermediates to pharmaceutical industry and universal chemicals to the chemical industry. We satisfy our customers with our global ability and we offer high quality with competition.
- What is dopamine modified Dopo da for flame retardant thermosetting epoxy resins?
- The flame retardant mechanism of flame retardant was analyzed. DOPO-DA promotes the curing process and improves the mechanical properties. In this work, we synthesized a 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOPO) derivative flame retardant dopamine modified DOPO (DOPO-DA) for flame retardant thermosetting epoxy resins (EP).
- Are Dopo-derivatives a suitable alternative to halogenated flame retardants?
- DOPO-derivatives are considered as suitable alternative to halogenated flame retardants because of their versatile flame extinguishing behavior in gas phase and condensed phase . Despite a growing interest in DOPO-derivatives as flame retardants , there exist no comprehensive review on their synthesis and application.
- Do Dopo-based flame retardants have a higher flame retardancy efficiency?
- DOPO-based flame retardants with P-N bonds were demonstrated to own a higher flame retardancy efficiency, especially in gas-phase flame retardancy . Therefore, adjusting the chemical structure of flame retardants has become a key factor in improving their efficiency and increasing their functionality.
- Which flame retardant is best for EP?
- Only 0.186 wt% phosphorus loaded flame retardant effectively improves the flame retardancy of EP, and the composites can pass the UL-94 V-0 level. Jian et al. prepared a flame retardant DOPO-ABZ containing P/N/S by introducing P-N bonds on DOPO substituents.
