Used as a high-performance flame retardant in engineering plastics and thermosetting resins. It is particularly effective in polycarbonates and polyesters, where it provides excellent thermal stability and flame resistance without compromising mechanical properties. Its sulfur-containing structure enhances char formation during combustion, reducing smoke and preventing the spread of flames. Commonly found in electronic components, automotive parts, and electrical enclosures where fire safety is critical. Also exhibits good compatibility with other additives, making it suitable for use in flame-retardant compound formulations.
