Description

2,2',3,4,4',6,6'-Heptabromodiphenyl Ether is a specific, highly brominated congener of the polybrominated diphenyl ether (PBDE) family, known for its significant flame-retardant properties. This compound is critical for industrial formulators requiring high thermal stability and effective fire suppression in demanding polymer matrices. It is primarily utilized by manufacturers in the plastics, textiles, and electronics industries seeking to enhance the fire safety of their materials while meeting specific regulatory and performance benchmarks.

Application

• As a flame retardant additive in engineering thermoplastics such as ABS, HIPS, and polyamides.
• In the formulation of fire-resistant coatings and paints for industrial and construction materials.
• For enhancing the fire safety of textile back-coatings used in upholstery, curtains, and protective fabrics.
• As a component in flame-retardant masterbatches for compounded polymer systems.
• In the production of electronic components and casings where regulatory fire safety standards (e.g., UL 94) must be met.
• For research and development purposes as a reference standard or analytical standard in environmental and regulatory testing.
