Technical Details & Test Data

Flame Retardancy Data of YX8800


 

Mechanism of flame retardancy

  • Step 1. Carbonized layer is formed.
  • Step 2. Heat insulating layer is formed.
  • Step 3. Heat and air are kept out.
  • Finally fire/flame is extinguished.


Model encapsulant composition

  • Hardener : Phenol aralkyl, Accelerator Triphenylphosphine (2phr)
  • Release agent : Carnauba wax (1phr)
  • Coupling agent : Epoxy silane (1phr)
  • Filler (Fused silica) Content : 85%, 175°C 200sec+8hr

Typical Reactions with Self Polymerization

Selection of Hardeners

Appropriate choice of Hardener for a desired curing temperature

General Ways to Use Epoxy
  • Epoxy resin forms 3D crosslinked network structure
  • Abundant choices of Epoxy/Hardener combination
