High-purity antimony trioxide
1. Product Quality:
Grade Sb2O3 PbO CuO As2O3 Fe2O3 Se Cd
High-purity grade ≥99.90% ≤0.005% ≤0.0009 ≤0.005 ≤0.005 ≤0.0008 ≤0.0005
3. Product Applications:

1. Utilized by plastic processors as a synergistic flame retardant in thermoplastic and thermoset formulations, with applications spanning transportation, construction and structural materials, electrical appliances, wires and cables, and furniture across various industrial sectors;
2. Employed by rubber processors in flame-retardant rubber products, including rubber hoses, belts, carpet backing, and other rubber goods;
3. Incorporated by automobile manufacturers in PVC seat covers, carpets, and other rubber components located within or beneath car hoods;
4. Indirectly utilized by synthetic fiber producers as a processing catalyst; antimony oxide plays a crucial role in the esterification process of polyethylene terephthalate resins and fibers;
5. Applied by glass manufacturers as an oxidation-reduction clarifying agent; in the glass coloring process, antimony oxide reduces specific metals (including iron, manganese, and chromium), thereby lowering their valence states to achieve enhanced glass coloration;
6. Used by ceramics and glaze producers as a bright, transparent white pigment embedded in glass or oil-based materials; this pigment is extensively employed in enameled cast iron bathtubs;
7. Utilized by paint manufacturers for flame-retardant white pigments, and when combined with other metals, it produces yellow pigments designated as 41, 53, and 118;
8. Employed by paper product manufacturers as a critical component in flame-retardant papers, which are applicable in household insulation products;
9. Used by chemical producers to manufacture a specialized heat stabilizer (thiol antimony) for PVC, approved by the FDA; also serves as an intermediate in both organic and inorganic compounds, and is utilized by phosphor lamp manufacturers to activate calcium halophosphate phosphor;
10. Applied by solid lubricant manufacturers as a synergist for molybdenum disulfide, contributing significantly to aerospace lubrication systems.

4. Product Packaging:

Moisture-proof inner plastic and outer paper packaging, with a net weight of 25KG per bag.
