Deca-BDE is a traditional brominated flame retardant widely used in thermoplastics and textiles. It delivers excellent flame resistance and is known for its cost-effectiveness and performance in electrical, automotive, and construction materials.
While its use is restricted or phased out in some regions due to regulatory concerns, it remains in use in specific industrial applications where alternatives are limited or still under evaluation.
