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
Bi-DOPO Structure Flame Retardants with or without Reactive
A novel reactive phosphorus-containing flame retardant 1,4-phenylene-bis((6-oxido-6H-dibenz[c,e][1,2]-oxaphosphorinyl) methylene) diacrylate (TDCAA-DOPO), with two symmetrical 9,10-dihydro-9-oxa-10-phosphaphena-nthrene-10-oxide structure (bi-DOPO), was synthesized and combined with unsaturated polyester resin (UPR) via cross-linking to prepare
successfully launched industrial production of new flame
Hunan Chemical BV successfully launched industrial production of new flame retardant for new flame retardant: Hexaphenoxycyclotriphosphazene which is halogon-free and no pollutant when burning, we have launched successfully industrial production in our plant, more important is our costs is affordable for industry now by our new production
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
- 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.
- Can disubstituted p -hydroquinone be used as a flame retardant?
- Proposed mechanism for synthesis of disubstituted p -hydroquinone. Compound 2 is a reactive monomer, Owing to the diol functionality. Therefore, it could be incorporated into the molecular backbone of polymers for flame retardant application.
- 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.
- Which phosphorous phosphate ester is best for flame retarding?
- 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. Tests show that EVERFOS DOPO has a less smoke density besides no corrosive gases for molders or extruders, is also suitable for high TG applications for resin and thermoplasts.
- Is compound 19 a flame retardant?
- Additionally compound 19 was investigated as active flame retardant in combination with 4,4′-diaminodiphenylmethane (DDM) in E51 epoxy resin. With increasing wt% of P-content in the resin, both char yield and LOI values were increased. By varying of P-content increased from 0 to 1.7%, LOI values improved from 24.5 to 33.5%.
