Description

End Capped And Partially End Capped Brominated Epoxy Oligomer is a specialized flame-retardant additive engineered for high-performance polymer systems. This product is critical for manufacturers requiring enhanced fire safety without compromising the mechanical or thermal properties of the base resin. It is primarily utilized by formulators and compounders in the electronics, construction, and transportation industries seeking reliable halogenated flame retardants.

Application

• As a reactive or additive flame retardant in epoxy resin systems for printed circuit boards (PCBs) and semiconductor encapsulation.
• Formulation of flame-retardant composites and coatings for construction materials and automotive components.
• Enhancing the fire resistance of engineering thermoplastics, such as polybutylene terephthalate (PBT) and polyamide (PA).
• Use in adhesives and potting compounds where UL94 V-0 ratings are required.
• Manufacture of fire-safe laminates for aerospace and mass transit interiors.
