Antimony Trioxide (ATO), with the chemical formula Sb2O3 and CAS number 1309-64-4, stands as a pivotal additive in modern manufacturing, particularly for its remarkable properties as a flame retardant synergist. For procurement professionals and product developers, understanding its multifaceted utility and sourcing it effectively is key to ensuring product safety and performance.

As a leading supplier in the chemical industry, we highlight the fundamental role ATO plays. Its primary function is to work in conjunction with halogenated compounds, such as brominated and chlorinated materials. During a fire, ATO reacts with these halogens to form antimony halides. These compounds are highly effective in interrupting the combustion process in several ways: they cool the flame through endothermic reactions, dilute combustible gases, and trap free radicals that propagate the burning process. This synergistic effect significantly enhances the fire resistance of materials where it is incorporated.

The key application areas where Antimony Trioxide delivers significant value include:

  • Plastics and Polymers: ATO is crucial for imparting flame retardancy to a wide range of polymers, including PVC, polyethylene, polypropylene, and ABS. This is essential for applications in consumer electronics, automotive components, wire insulation, and construction materials, where fire safety standards are stringent.
  • Coatings and Paints: Beyond its flame-retardant capabilities, ATO is also utilized as a white pigment and opacifier in paints and coatings, contributing to their brightness, opacity, and durability.
  • Textiles: It is used to treat fabrics and fibers to improve their fire resistance, making them suitable for applications in upholstery, curtains, and protective clothing.
  • Glass Manufacturing: ATO serves as an effective clarifying agent in the production of glass, aiding in the removal of bubbles and improving the optical clarity and brilliance of the final product.
