Features Of Epoxy Resin Flame Retardant

  1. Halogen-free formulation meeting stringent RoHS and REACH compliance requirements.

  2. Excellent thermal stability with decomposition onset above 300 °C.

  3. Maintains high glass transition temperature (Tg) of cured epoxy systems without compromising mechanical strength.

  4. Good compatibility with standard DGEBA-type epoxy resins and common hardeners.

  5. Enables UL 94 V-0 rating at low additive loading (typically 15–20 wt% in formulated resin).

Typical Applications Of Epoxy Resin Flame Retardant

  1. Printed circuit board (PCB) laminates requiring high flame retardancy and dimensional stability.

  2. Electrical encapsulation compounds for power modules, transformers, and LED drivers.

  3. Composite matrices in aerospace interior components meeting FAR 25.853 smoke and toxicity standards.

  4. High-performance adhesives for electronics assembly and electric vehicle battery module bonding.

  5. Structural potting resins used in industrial control cabinets and renewable energy inverters.
