Decabromodiphenyl ethane is a widely used broad-spectrum additive flame retardant with high bromine content, excellent thermal stability, and superior UV resistance. It exhibits lower migration compared to other brominated flame retardants and is particularly suitable for flame-retarding high-grade materials used in computers, fax machines, telephones, copiers, household appliances, etc.

Decabromodiphenyl ethane is a widely used broad-spectrum additive flame retardant with high bromine content, excellent thermal stability, and superior UV resistance. It exhibits lower migration compared to other brominated flame retardants and is particularly suitable for flame-retarding high-grade materials used in computers, fax machines, telephones, copiers, household appliances, etc.
Decabromodiphenyl ethane does not produce toxic polybrominated dibenzo-p-dioxins (PBDDs) or polybrominated dibenzofurans (PBDFs) during thermal decomposition or combustion. Materials flame-retarded with it fully comply with European regulations on dioxins and pose no harm to the environment.
Decabromodiphenyl ethane is non-toxic, non-teratogenic to organisms, and has no adverse effects on aquatic life such as fish, meeting environmental protection requirements.
Decabromodiphenyl ethane remains highly stable in application systems, and thermoplastic plastics flame-retarded with it can be recycled.
Decabromodiphenyl ethane has a lesser adverse impact on the properties of flame-retarded materials compared to the traditional flame retardant decabromodiphenyl ether, with better light resistance and lower migration.

Decabromodiphenyl ethane is a new type of broad-spectrum, efficient, and environmentally friendly additive flame retardant developed in recent years. Its heat resistance, light resistance, and low migration are superior to those of decabromodiphenyl ether. While both have similar flame retardancy, decabromodiphenyl ethane does not produce the concerning polybrominated dioxins during combustion and is less toxic than decabromodiphenyl ether. Although decabromodiphenyl ether was exempted in October 2005, it may still face potential bans in the future. Therefore, decabromodiphenyl ethane serves as an excellent alternative. It is suitable for adhesives and sealants such as polystyrene, high-impact polystyrene, ABS, epoxy resins, and elastomers.
