DOPO flame retardant powder (CAS 35948-25-5), chemical name 9,10-Dihydro-9-oxa-10-phosphaphenanthrene-10-oxide, is high purity white crystalline reactive organophosphorus powder. It has active P-H bond that can covalently react with epoxy groups and functional groups of adhesives during curing process. Unlike additive flame retardants, it is locked inside polymer network and will not migrate or bloom on surface. This powder grade is widely used in epoxy resin and structural adhesive formulations

Product Detail

Product DetailsChemical IdentityProduct Name: 9,10-Dihydro-9-oxa-10-phosphaphenanthrene-10-oxide, DOPO CAS No.: 35948-25-5 Chemical Type: Reactive halogen-free organophosphorus compound Physical Form: White crystalline powder Core Feature: High purity reactive phosphorus powder for epoxy resin and adhesive

Key Performance & TDSThis DOPO powder has fine crystalline particle size for easy dispersion in epoxy and adhesive systems. Its reactive P-H functional group participates in crosslinking reaction and integrates into polymer molecular chain permanently. It provides excellent flame suppression performance and helps cured epoxy or adhesive products achieve UL94 V-0 rating. It features high thermal stability, low smoke emission upon combustion. Halogen-free composition avoids corrosive gas release under fire condition. It has minimal negative impact on bonding strength of structural adhesives and dielectric properties of cured epoxy resin. High purity reduces impurities, lowering the risk of discoloration and performance degradation of finished products.

Applications

Flame retardant modification of liquid and solid epoxy resin
Epoxy structural adhesive and construction adhesive formulation
Thermosetting adhesive for electronic assembly
Halogen-free epoxy casting and potting compounds
Adhesive systems requiring permanent non-migratory flame retardancy

ComplianceThis product complies with RoHS and REACH regulations, suitable for global export epoxy and adhesive raw material projects.
