Reliable supply of industrial-grade antimony trioxide for flame-retardant polymer systems, PVC compounds, rubber, textiles, coatings, glass and ceramic applications.
Antimony trioxide, also known as diantimony trioxide or antimony(III) oxide, is a white inorganic powder with the chemical formula Sb₂O₃. Its principal industrial application is as a synergist in halogenated flame-retardant formulations.
When used together with suitable halogen-containing components, antimony trioxide helps improve the fire performance of plastics, rubber, textiles, coatings and other polymer systems. It is also used as a functional or opacifying additive in selected glass, ceramic and enamel applications.
Tradege supplies TR-001 grade antimony trioxide for industrial manufacturers, compounders, masterbatch producers and chemical distributors.
With a minimum Sb₂O₃ assay of 99.65%, the product is suitable for general industrial flame-retardant formulations and selected glass, ceramic, coating and compound applications. Technical documentation, export documentation and international delivery options are provided according to the destination market and order requirements.
For application-specific evaluation, customers are advised to review the particle-size distribution, impurity limits, formulation compatibility and required regulatory documentation before placing an order.
