Brominated Epoxy Resin Flame Retardant

Featured inFlame Retardants

Brominated epoxy resin (BER) is a high-bromine-content reactive and additive flame retardant used in epoxy laminates, adhesives, and thermoplastics. Based on brominated bisphenol A diglycidyl ether oligomers, it integrates into the epoxy cure cycle, providing durable, non-migratory flame retardancy. BER is widely used in PCB epoxy systems, HIPS, and polyester as either a reactive component (with epoxy systems) or an additive (with thermoplastics), offering an intermediate approach between fully reactive TBBPA and additive halogen FRs.

Uygulama Alanları

  • FR-4 and FR-5 epoxy PCB laminate manufacture as reactive FR component
  • HIPS and polystyrene compounds as additive flame retardant with Sb2O3
  • Epoxy powder coating resins requiring UL94 V-0 flame classification
  • Polyester film and fiber with brominated FR requirements
  • Adhesive and potting compound systems requiring halogenated FR

Ürün Özellikleri

  • Dual use as both reactive (epoxy systems) and additive (thermoplastics) FR reduces inventory complexity
  • High bromine content (48–52%) achieves UL94 V-0 in PCB epoxy and HIPS at practical loading levels
  • Reactive epoxy groups allow covalent incorporation, providing migration-resistant FR in laminate systems
  • Good thermal stability and compatibility with standard epoxy hardeners and HIPS processing conditions
