Resorcinol Bis(diphenyl phosphate) (RDP) is an organophosphorus compound widely used as a flame retardant in various industrial applications, particularly in the manufacturing of electronics, plastics, and textiles. RDP provides effective flame resistance by promoting char formation and inhibiting the spread of flames, helping to meet stringent fire safety standards. It is favored for its thermal stability, low volatility, and compatibility with different polymers. Additionally, RDP is often chosen for its reduced environmental impact compared to other flame retardants, making it a preferred choice in sustainable product development.
