Exceptional Reducing Power for Industrial Applications

Sodium Hydro Sulphite is renowned for its potent reducing capabilities, making it indispensable in textile processing, paper bleaching, and water treatment. Its rapid action ensures efficient color removal and reduction reactions, contributing to superior industrial outcomes and reliable processes across multiple sectors.

Safe Handling and Storage Guidelines

Due to its unstable nature and susceptibility to air and moisture, Sodium Hydro Sulphite must be stored in tightly sealed containers in cool, dry environments. Proper handling reduces the risk of spontaneous decomposition, toxic exposure, and ensures both worker safety and product longevity, with a shelf life up to 12 months under optimal conditions.

Regulatory Compliance and Responsible Packaging

Our Sodium Hydro Sulphite complies with textile and industrial chemical standards, guaranteeing both efficacy and safety. The product is packaged in UN-approved, hazard-labeled containers tailored to international transport regulations, ensuring secure delivery and easy identification during transit.

FAQs of Sodium Hydro Sulphite:

Q: How should Sodium Hydro Sulphite be stored to maintain its stability and shelf life?
