      Product Detail  


    Sodium Thiosulphate (commonly called Hypo), molecular formula Na₂S₂O₃, CAS 7772-98-7, molecular weight 158.11, is high-purity inorganic reducing agent with industrial grade minimum purity 99%. It is produced by soda ash, sulfur and sulfur dioxide synthesis, followed by evaporation crystallization, centrifugal separation and drying treatment to form uniform white transparent crystalline particles without yellow or black impurity particles.
    The crystal grain size is moderate, free-flowing, low dust during feeding, dissolves rapidly and completely in clean water to form clear aqueous solution with weak alkaline property. It has strong selective reducibility, can quickly react with residual chlorine, heavy metal ions and oxidizing substances in industrial wastewater, effectively removing chroma and reducing COD value to meet sewage discharge standards. Different from sodium metabisulfite, sodium thiosulphate has milder reaction, no obvious sulfur dioxide gas released during use, better operating environment and less corrosion to equipment.
    In mineral processing industry, it serves as environment-friendly reducing leaching auxiliary for gold ore, replacing part of toxic cyanide reagents to improve gold recovery rate. For textile printing and dyeing factories, it acts as deoxidizer after hydrogen peroxide bleaching to prevent fabric fiber yellowing and protect dyed color brightness. It is also classic photographic fixing raw material, which can dissolve unexposed silver halide on film and photo paper to fix image permanently. In leather and papermaking industries, it works as bleaching auxiliary to reduce fiber damage.
    This product has stable chemical properties under sealed dry storage, not easy to oxidize and agglomerate. Every batch passes full laboratory testing of purity, water insoluble matter, iron, heavy metal and moisture before shipment. Finished goods adopt double-layer packaging: inner PE plastic liner + outer woven bag to isolate moisture and air during long-distance sea transportation. We support small trial orders and ton bulk bag shipments, and can provide complete COA, MSDS and third-party impurity inspection reports for global water treatment plants, mineral processing factories and printing enterprises.
    • High purity ≥99%, ultra-low iron, heavy metal and water insoluble impurities, crystal bright white without discoloration.
    • Fast full water solubility, clear solution without sediment, stable continuous reduction effect.
    • Mild reaction process, no irritating sulfur dioxide gas overflow during application, better workshop operating environment.
    • Multi-scenario industrial use: wastewater dechlorination, gold ore flotation, textile bleaching, photographic fixing agent.
    • Moderate crystal particle size, low dust, free-flowing, convenient for automatic feeding equipment.
    • Good oxidation resistance under sealed storage, not easy to deteriorate within shelf life.
    • Moisture-proof double-layer packaging, flexible packaging specifications for different order quantities.
    • Complete export certification documents to support smooth customs clearance.Shop Sodium Thiosulfate Hypo 99% Industrial Raw Material Reducing Agent For Printing Dyeing Gold Leaching Water Treatment-Detailed Image 1
