Description

Bis(2,3-Epoxypropyl) 3,4,5,6-Tetrabromophthalate is a halogenated epoxy ester compound, primarily valued as a highly effective reactive flame retardant additive. Its molecular structure allows it to be chemically incorporated into polymer matrices, providing durable flame resistance without compromising the mechanical properties of the final material. This product is essential for manufacturers in the electronics, construction, and advanced composite materials industries seeking to meet stringent fire safety regulations.

Application

• Reactive Flame Retardant for Epoxy Resins: Chemically bonds into epoxy systems for printed circuit boards (PCBs), semiconductor encapsulants, and electrical laminates, providing non-plasticizing, permanent flame retardancy.
• Thermoset Composites: Used in fiber-reinforced plastics (FRP) for construction, transportation, and aerospace applications where high fire safety standards (e.g., UL 94 V-0) are required.
• Adhesives and Coatings: Imparts flame-retardant properties to high-performance industrial adhesives and protective coatings.
• Polymer Modification: Serves as a reactive intermediate for synthesizing specialty polymers with inherent flame-retardant characteristics.
