Antimony Trioxide (Sb₂O₃) or ATO is a versatile inorganic compound universally used across multiple industrial sectors, primarily as a flame retardant. Predominantly utilised in the production of plastics, textiles, glass, and electronic components. Antimony Trioxide main role is as a synergist in halogenated flame retardant systems for various applications, where it enhances the material’s flame resistance. For clarity in trade and sourcing, Antimony Trioxide is also called by other names, such as Diantimony Trioxide and Antimonious Oxide, terms often used by ATO manufacturers. Offered Antimony Trioxide as an end-to-end product solution and competitive pricing on ATO grades. We are a globally established Antimony Trioxide manufacturer and various flame-retardant supplier.
