CAS Number: 1163-19-5

Decabromodiphenyl ether (Deca-BDE) is a highly brominated additive flame retardant with 83.3% bromine content, historically one of the most widely used halogenated FRs in high-impact polystyrene (HIPS), ABS, and nylon. It functions primarily in the gas phase by releasing HBr radicals that interrupt combustion chain reactions. Note: Deca-BDE is restricted under EU REACH SVHC and listed in Annex A of the Stockholm Convention on Persistent Organic Pollutants; buyers must verify applicable regional regulatory status before procurement.

Nylon PA6/PA66 electrical components in non-EU legacy applications
Textile and fabric back-coating for drapery and upholstery in certain jurisdictions
Rubber and elastomer compounding where halogenated FRs are permitted

Key Features

Highest bromine content (83%) among diphenyl ether FRs provides maximum halogen-based flame suppression efficiency
High thermal stability (stable to 300 °C) compatible with HIPS, ABS, and nylon processing temperatures
Synergistic with antimony trioxide at 3:1 (BDE:Sb2O3) ratio for maximum gas-phase FR effectiveness
Cost-effective halogenated FR option for markets where brominated FRs remain permitted
