Antimony Trioxide
Antimony Trioxide (Sb2O3, CAS 1309-64-4) is a white crystalline powder supplied by Shijiazhuang Kunmai Chemical Technology Co., Ltd. from Hebei, China. It is insoluble in water but soluble in acid and sodium hydroxide solutions, making it a versatile industrial chemical. The compound is primarily used as a flame retardant synergist in plastics, textiles, and coatings, where it enhances opacity and UV resistance in paints and polymer applications.
As a pigment, Antimony Trioxide provides excellent coverage and brightness, while its flame-retardant properties are amplified when combined with other additives, creating a synergistic effect. It is also a critical input for PVC stabilization and polyester catalyst production, with applications in petrochemicals, synthetic rubber, and canvas manufacturing. In the enamel industry, it serves as an additive to improve opacity and surface gloss, while in glass production, it acts as a bleaching agent, replacing arsenious acid.
Global buyers source this product for use in flame-retardant formulations, pigment production, and chemical catalysis. The material is typically traded in bulk, with packaging and lead times confirmed directly with the supplier. Its compliance with origin and purity certifications is essential for regulated export markets, particularly in Europe and North America where chemical safety standards are stringent.
