Description

Tetrabromobisphenol A Diglycidyl Ether is a brominated epoxy resin intermediate, primarily valued for its role as a reactive flame retardant. This compound is essential for manufacturers requiring enhanced fire safety properties in polymer systems without compromising the material's structural integrity. It is a critical raw material for industries producing printed circuit boards, electronic encapsulants, and high-performance composite materials.

Application

• As a reactive flame retardant in epoxy resin systems for printed circuit boards (PCBs).
• In the formulation of flame-retardant coatings and adhesives.
• As a key intermediate for brominated epoxy resins used in electronic encapsulation.
• For enhancing the fire resistance of composite materials and laminates.
• In the production of specialty polymers requiring high thermal stability and flame retardancy.

Quality Control

Our Tetrabromobisphenol A Diglycidyl Ether is manufactured under a stringent quality management system. Each batch undergoes comprehensive analytical testing to ensure consistent purity, reactivity, and performance. A Certificate of Analysis (COA) detailing key parameters such as epoxy value, bromine content, and hydrolyzable chlorine is provided with every shipment to guarantee supply reliability and product consistency for your formulations.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from heat sources and incompatible materials. Due to its light-sensitive nature, containers should be kept in the original packaging or opaque containers until use.
