Decabromodiphenyl ether

CAS: 1163-19-5

Overview

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

Decabromodiphenyl oxide is the alternate name most frequently encountered in technical specifications and compliance documentation. It functions by interrupting combustion in the gas phase, enabling treated materials to achieve required flammability ratings.

In plastics and polymer compounding, DecaBDE is incorporated into ABS, HIPS, and polyolefin formulations used in electronic housings, connectors, and cable jacketing.

Textile and upholstery manufacturers apply it to back-coatings on curtains, seating fabrics, and protective workwear where fire performance standards must be met.

Automotive and aerospace component suppliers use it in interior trim materials, wire insulation, and structural composites requiring UL 94 or equivalent certification.

Building and construction applications include flame-retarded panels, insulation facings, and roofing membranes where fire classification is a procurement requirement.

DecaBDE is supplied as a white to off-white powder or as masterbatch pellets for direct compounding use. Technical-grade material is the standard commercial form, with purity typically specified at 97% or higher.

Bulk supply is available in bags and supersacks, with some suppliers offering pre-compounded concentrates for specific polymer systems to ensure uniform dispersion during manufacturing.
