Decabromodiphenyl ether

Decabromodiphenyl ether (CAS 1163-19-5), commonly known as DecaBDE or BDE-209, is a brominated flame retardant used in polymer-intensive industries to meet fire safety and regulatory standards. Also called decabromodiphenyl oxide.

Where is Decabromodiphenyl ether used?

• Plastics and polymer compounding: incorporated into ABS, HIPS, and polyolefin formulations for electronic housings, connectors, and cable jacketing
• Textiles and upholstery: back-coatings on curtains, seating fabrics, and protective workwear
• Automotive and aerospace: interior trim materials, wire insulation, and structural composites requiring UL 94 or equivalent certification
• Building and construction: flame-retarded panels, insulation facings, and roofing membranes
• It interrupts combustion in the gas phase, enabling treated materials to achieve required flammability ratings.

Commercial specifications

• Purity typically 97% or higher
• Bulk supply in bags and supersacks
• Pre-compounded concentrates offered for specific polymer systems to ensure uniform dispersion
