DBDPO (Decabromodiphenyl Oxide) is a white to off-white powder with a molecular weight of 959.9 g/mol. It is commonly used as a flame retardant in various applications such as plastics, textiles, and electronics due to its excellent fire-resistant properties. In terms of hazard identification, based on the NFPA-704 M Rating System, it is classified as Health 2, Flammability 0, and Reactivity 0, indicating it presents a moderate health hazard, but is not flammable or reactive under typical conditions. DBDPO is only slightly soluble in water, making it less likely to leach out in aqueous environments. However, proper handling is necessary to avoid health risks, especially in large-scale industrial settings.

Decabromodiphenyl oxide is an inert, additive-type flame retardant known for its excellent thermal stability and cost-effectiveness. It is extensively applied in thermoplastic and thermoset resins, textiles, and adhesives. Key applications include high-impact polystyrene, glass-filled thermoplastic polyester and molding compounds, low-density polyethylene extrusion coatings, polypropylene (both homopolymers and copolymers), acrylonitrile butadiene styrene (ABS), nylon, and polyvinyl chloride (PVC).
