Bisphenol A Bis(diphenyl phosphate) is primarily used as a flame retardant in various polymer materials, including engineering plastics, coatings, and adhesives. It is particularly effective in enhancing the fire resistance of polycarbonate and acrylonitrile butadiene styrene (ABS) resins, which are commonly used in electronic devices, automotive components, and construction materials. Its ability to inhibit combustion and reduce smoke emission makes it a valuable additive in applications where fire safety is critical. Additionally, it is utilized in the production of flame-retardant textiles and foams, contributing to improved safety standards in industries such as furniture manufacturing and insulation. Its compatibility with other additives and stability under processing conditions further broadens its utility in diverse industrial applications.
