NINGBO INNO PHARMCHEM CO.,LTD. is a trusted provider of high-quality chemical raw materials for global industries. We are pleased to highlight one of our key offerings: high-purity Antimony Trioxide, represented by the chemical formula Sb2O3. This versatile inorganic compound is a cornerstone in numerous manufacturing processes.

Antimony Trioxide is predominantly supplied as a fine white powder, making it easy to incorporate into various formulations. Its physical and chemical properties underscore its value in demanding applications. It possesses a molecular weight of 291.52, a melting point of 656ºC, and a boiling point of 1425ºC. The specific gravity stands at 5.2. Sb2O3 exhibits solubility in HCl and tartaric acid but is notably insoluble in water and acetic acid. Our industrial grade material typically boasts a purity level of 99.8%.

The applications of Antimony Trioxide are extensive and critical. Primarily, it serves as a crucial synergist in halogen-based flame retardant systems. When combined with halogenated compounds, it significantly enhances the fire resistance of polymer materials such as PVC, PP, PE, PS, ABS, and PU. This makes it indispensable in manufacturing products requiring strict fire safety standards, including electric device enclosures and household appliances.

Beyond flame retardation, Antimony Trioxide finds significant use as a clarifier additive in glass manufacturing, helping to remove bubbles and improve transparency. In the ceramics and enamel industries, it acts as a pigment and opacifier. Furthermore, it is incorporated into paints and coatings as both a pigment and a retardant, contributing to durability and safety. Its utility extends to rubber, fabrics, and fiber products as a filling, covering, and retardant agent. Antimony Trioxide is also utilized as a retardant in synthetic resin and paper production, and importantly, it can function as a catalytic agent in various organic synthesis reactions.

The role of Antimony Trioxide as a fundamental raw material cannot be overstated. Its multifaceted properties make it essential for improving the performance and safety characteristics of a wide array of finished goods across diverse sectors, from electronics and construction to textiles and automotive. Its consistent quality is paramount for ensuring predictable outcomes in complex industrial processes.
