Description

2,5-Furandione, Polymer With 2,2-Bis(Bromomethyl)-1,3-Propanediol, 1,2-Ethanediol And 3A,4,7,7A-Tetrahydro-4,7-Methano-1H-Indene CAS NO 79459-49-7 is a specialized brominated polymeric flame retardant additive. This compound is engineered to provide exceptional fire resistance and thermal stability to polymer matrices, making it a critical component for enhancing material safety. It is primarily sought by manufacturers in the plastics, coatings, and electronics industries who require high-performance, halogenated flame retardants that meet stringent safety regulations.

Application

• Flame Retardant for Engineering Plastics: Imparts fire resistance to polyamides (nylon), polyesters (PBT, PET), and polycarbonate blends used in electrical components and automotive parts.
• Additive for Thermoset Resins: Used in epoxy and unsaturated polyester resins for printed circuit boards (PCBs), electrical laminates, and composite materials.
• Protective Coatings and Paints: Enhances the fire retardancy of industrial and architectural coatings, particularly for applications requiring low smoke emission.
• Wire and Cable Insulation: A key additive in polyethylene (PE) and polyvinyl chloride (PVC) formulations to meet fire safety standards for building and transportation wiring.
• Synthetic Rubber and Elastomers: Improves the flame resistance of rubber compounds used in seals, gaskets, and specialized industrial hoses.
• Adhesives and Sealants: Incorporated into formulations where enhanced fire performance is required without severely compromising mechanical properties.

Quality Control

Our flame retardant products undergo rigorous quality testing to ensure batch-to-batch consistency and compliance with industry standards such as UL 94 and IEC 60695. Key parameters including bromine content, thermal stability, and viscosity are strictly monitored. Certificates of Analysis (COA) detailing purity, physical properties, and performance data are available upon request to support your quality assurance protocols.

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 oxidizing agents. The container must be kept tightly closed to prevent moisture absorption.
