Description

Tetrabromobisphenol-A Diglycidyl Ether Polymer is a brominated epoxy resin oligomer, primarily valued for its role as a highly effective reactive flame retardant. This compound is critical for enhancing the fire safety of polymer materials without significantly compromising their mechanical properties. It is essential for manufacturers in the electronics, construction, and transportation industries who require durable, flame-retardant thermoset composites and coatings.

Application

• As a reactive flame retardant in epoxy resin systems for printed circuit boards (PCBs) and semiconductor encapsulation.
• In the formulation of flame-retardant coatings and adhesives for construction materials and automotive components.
• As an additive in vinyl ester and unsaturated polyester resins for fiber-reinforced plastics (FRP) used in marine and transportation applications.
• For enhancing the fire resistance of engineering thermoplastics and thermosets in electrical connectors and housings.
• In the production of fire-safe composite materials for aerospace and mass transit interiors.
• As a key intermediate in the synthesis of other advanced brominated flame retardants.

Quality Control

Our Tetrabromobisphenol-A Diglycidyl Ether Polymer is manufactured under a strict quality management system. Each batch is tested to ensure consistent bromine content, epoxy value, viscosity, and hydrolyzable chlorine levels, meeting the stringent requirements of the electronics and composite industries. Certificates of Analysis (COA) detailing purity and key parameters are available upon request.

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 such as strong acids and bases. This material is hygroscopic (moisture-sensitive); ensure containers are sealed after use to prevent moisture absorption.
