简体中文Epoxy Resin Flame Retardants
-- Steady & Reliable Manufacturer --
Introduction
Epoxy resins are used across electronics, composites, and structural applications where fire performance is often just as important as mechanical and electrical properties. Flame retardants for epoxy resin are reactive or additive chemistries built into epoxy systems to reduce flammability while preserving cure behavior, dielectric performance, and mechanical strength.
As a manufacturer, we supply DOPO-based reactive flame retardants, phosphate ester additive systems, and mineral-based options suited to copper clad laminates, potting and encapsulation compounds, structural composites, and protective coatings. Product selection depends on whether the flame retardant needs to react into the epoxy backbone or simply blend into the formulation.
Because epoxy systems are frequently used in electronics and structural parts with long service lives, compatibility with standard curing agents, minimal impact on glass transition temperature, and stable dielectric performance are treated as baseline requirements.
Specification
| Parameter | Typical Value |
|---|---|
| Appearance | White powder, pale yellow flake, or liquid depending on grade |
| Chemical Type | DOPO-based reactive system or additive phosphate ester system |
| Phosphorus Content | Typically 6% to 10%, grade dependent |
| Melting Point (solid grades) | 90°C to 120°C, grade dependent |
| Viscosity (liquid grades, 25°C) | 200 to 2000 mPa·s |
| Moisture Content | 0.3% max |
| Epoxy Equivalent Weight Compatibility | Suitable for standard DGEBA and DGEBF systems |
| Packaging | 25kg fiber drums, 25kg bags, or 200kg drums for liquid grades |
Reactive and additive grades behave differently during formulation and cure; our technical team can advise on the correct grade and loading level for your specific epoxy system and target flammability rating.
Application
These flame retardants are formulated into epoxy systems used across electronics, composites, and industrial applications.
- Copper clad laminates (CCL): Flame retardant systems for PCB substrates requiring UL94 V-0 performance.
- Electronic potting and encapsulation compounds: Resins used to protect sensitive electronic components.
- Structural composites: Wind turbine components, pipes, and reinforced structural parts.
- Adhesives and coatings: Epoxy-based adhesives and protective coatings requiring flame resistance.
- Insulating varnishes: Electrical insulation systems for motors and transformers.
Advantages
- UL94 V-0 support: Formulated to help finished epoxy parts and laminates reach V-0 classification at practical loading levels.
- Electronics-friendly: Selected grades are designed to minimize impact on dielectric strength and volume resistivity.
- Cure system compatibility: Suitable for use with standard amine and anhydride curing agents in common epoxy systems.
- Halogen-free options: DOPO-based reactive grades support RoHS and halogen-free supply chain requirements.
- Thermal stability during cure: Stable across typical epoxy cure temperature profiles without significant degradation.
