Antimony Trioxide (Sb₂O₃) is a versatile inorganic compound universally used across multiple industrial sectors, primarily as a flame retardant. (Sb₂O₃), commonly referred to as ATO and is predominantly utilized in the production of plastics, textiles, glass, and electronic components. Antimony Trioxide main role is 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 and Antimony Trioxide suppliers. At Scimplify, we offer Antimony Trioxide as an end-to-end product solution, leveraging the strength of our global network to provide competitive pricing and ensure supply chain reliability worldwide and in the united states.
