Description

Sodium Bisulfate is a versatile inorganic acid salt widely recognized for its efficacy as a pH adjuster, cleaning agent, and chemical intermediate. Its strong acidic nature in solution makes it a powerful and cost-effective alternative to mineral acids for numerous industrial processes. This compound is essential for manufacturers and processors in the water treatment, metal finishing, food processing, and cleaning product industries seeking reliable and consistent acidulation.

Application

• pH Control & Water Treatment: Used for lowering pH in swimming pools, industrial wastewater, and boiler feed water systems.
• Metal Surface Treatment: Employed in pickling and cleaning baths to remove rust, scale, and oxides from steel and other metals prior to plating or coating.
• Industrial & Household Cleaning: A key acidic component in toilet bowl cleaners, metal cleaners, and detergent formulations for effective descaling and stain removal.
• Food Processing: Approved as a food acidulant (E514) for pH adjustment, color retention, and as a leavening agent in certain baked goods.
• Chemical Manufacturing: Serves as a raw material and catalyst in the production of other chemicals, including dyes and pigments.
• Pulp & Paper Industry: Utilized in the bleaching process and for pH adjustment during pulp production.
• Textile Processing: Applied in dyeing and printing processes as an acidifying agent for color fixation.

Quality Control

Our Sodium Bisulfate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets precise chemical and physical specifications. While available in technical and food-grade (FCC) qualities, all products are supplied with a corresponding Certificate of Analysis (COA) to guarantee consistency, purity, and performance for your application.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong bases and oxidizing agents. Due to its hygroscopic (moisture-sensitive) nature, keep containers tightly sealed when not in use to prevent caking. Recommended storage temperature is 15-25°C.
