Zinc Borate Gains Traction in Engineering Plastics

Zinc borate is emerging as a key flame retardant in engineering plastics, particularly for Nylon 6 modification, according to industry sources. While halogenated zinc borate systems dominate domestic applications due to cost-effectiveness and high bromine content, they release toxic substances like dioxins during combustion.

Industry experts are developing eco-friendly alternatives to comply with EU RoHS/WEEE directives. Novel decabromodiphenylethane-based zinc borate offers improved thermal stability and light resistance without blooming issues, presenting a viable substitute for traditional halogenated variants. Red phosphorus-zinc borate combinations remain limited to black products, restricting their application scope.
