Description

1,3-Isobenzofurandione, 4,5,6,7-Tetrabromo-, Polymer With 2,5-Furandione, 1,3-Isobenzofurandione And 1,2-Propanediol is a specialized brominated polymeric compound designed for high-performance applications requiring flame retardancy and thermal stability. This engineered polymer is valued for its ability to impart significant fire resistance to various polymer matrices without compromising key material properties. It is primarily utilized by manufacturers in the electronics, construction, and advanced materials sectors seeking reliable halogenated flame retardant additives.

Application

• As a reactive or additive flame retardant in epoxy resin systems for printed circuit boards (PCBs) and electronic encapsulants.
• Enhancing the fire resistance of engineering plastics such as polyesters, polyamides, and polycarbonates used in automotive and electrical components.
• Formulation of fire-retardant coatings and paints for construction materials, cables, and textiles.
• Use in thermoset composites for aerospace, marine, and transportation applications where stringent fire safety standards apply.
• Potential component in specialty adhesives and sealants requiring improved flame retardant ratings (e.g., UL 94).
• Development of fire-safe synthetic polymers for consumer electronics housings and connectors.

Quality Control

Our production of this brominated polymer adheres to rigorous quality control protocols to ensure batch-to-batch consistency and performance reliability. Key parameters such as bromine content, acid value, viscosity, and thermal stability are strictly monitored. A comprehensive Certificate of Analysis (COA) detailing purity, physical properties, and performance characteristics is provided with every shipment to support your quality assurance and regulatory compliance needs.

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, the original container should be kept sealed until use to maintain product integrity.
