Application area

Decabromodiphenylethane is a new, broad-spectrum, efficient, and environmentally friendly additive flame retardant developed and produced in recent years. Its heat resistance, light resistance, and non dialysis properties are better than those of decabromodiphenyl ether. The flame retardancy of the two is basically the same, but it does not cause the concern of polybrominated dioxins when flame retardant, and its toxicity is lower than that of decabromodiphenyl ether. Although decabromodiphenyl ether was exempted in October 2005, the possibility of its production and use being banned after more than a decade is not ruled out. Therefore, decabromodiphenyl ethane is an excellent substitute for decabromodiphenyl ether. Decabromodiphenylethane is suitable for adhesives and sealants such as polystyrene, high styrene, ABS, epoxy resin, and elastomers.
