DOPO (9,10-Dihydro-9-oxa-10-phosphaphenanthrene-10-oxide) is a highly effective halogen-free flame retardant widely used in epoxy resin systems. Its unique phosphorus-containing heterocyclic structure provides excellent thermal stability (decomposition >300°C) and reactive sites for covalent bonding with epoxy matrices.
Key advantages in epoxy applications:
Reactive Functionality - Can chemically incorporate into epoxy networks as both flame retardant and curing agent modifier
High Efficiency - Achieves UL94 V-0 rating at 3-5% loading while maintaining mechanical properties
Thermal Performance - Enhances char formation and reduces heat release rate in cured resins
Electrical Properties - Maintains excellent dielectric characteristics for electronic applications
Primary epoxy uses include:
PCB laminates (replacing brominated systems)
Electronic encapsulants
Composite matrices
Electrical insulation materials
DOPO offers superior environmental and safety profiles compared to traditional brominated flame retardants, meeting strict RoHS and REACH requirements. Its reactive nature prevents migration and blooming issues common with additive-type flame retardants.
