Antimony trioxide

Antimony trioxide from Jiefu Corporation is a white powder with the molecular formula Sb2O3 and a molecular weight of 291.5, supplied as a flame retardant for industrial applications. The compound demonstrates a melting point of 656°C and a boiling point of 1425°C, confirming thermal stability suitable for high-temperature manufacturing environments. Its chemical structure makes it a reliable additive in processes where heat resistance and safety compliance are critical.

The product is used primarily in plastics, textiles, and electronics as a flame-retardant synergist, enhancing material safety without compromising performance. Standard grades for antimony trioxide typically feature a purity of 99% or higher, with particle sizes tailored to specific application needs such as coatings or polymer compounds. Industry practice often includes testing for arsenic content, which is standard to keep below 10 ppm, and ensuring low volatility to maintain consistency in end products.

Importers source this material for automotive, construction, and packaging sectors where regulatory safety standards demand non-combustible additives. Buyers commonly request confirmation of particle size distribution, which is standard in the 1-10 micron range for most industrial uses, and packaging options such as 25 kg bags or 1 tonne jumbo bags for bulk shipments. Lead times and incoterms are agreed directly with Jiefu Corporation, based in Shenzhen, China, with verification of certifications required before finalising orders.

Jiefu Corporation is based in Shenzhen, China, with its office located at 14F, China Nonfemet Building, No.6013 Shennan Road, 518040. The company operates as an imported-tier supplier, indicating it sources materials for international trade. Its profile does not state a response rate or average response time, which buyers should confirm directly for communication reliability.

The supplier’s listing specifies antimony trioxide as a key product, but does not provide additional details on certifications, production capacity, or client base. Buyers are advised to request documentation such as test reports, compliance certificates, and quality control procedures to verify the material’s suitability for their applications.
