Description

Sulfamic Acid is a versatile, strong inorganic acid known for its excellent descaling and cleaning properties, offering a safer and more convenient alternative to hydrochloric acid in many applications. Its non-volatile and crystalline nature makes it a critical raw material for producing stable chemical intermediates and effective cleaning formulations. This product is essential for industries ranging from industrial cleaning and water treatment to pulp & paper and textile manufacturing.

Application

• Industrial Descaling & Cleaning: Primary agent for removing lime scale, rust, and other mineral deposits from boilers, heat exchangers, cooling towers, and dairy equipment.
• Water Treatment: Used as a powerful yet safer acid cleaner for membrane systems (RO, UF) and as a precursor for chlorine stabilizers (e.g., sodium sulfamate).
• Pulp & Paper Industry: Employed as a pulp bleaching agent, a stabilizer for chlorine dioxide, and for pH control in paper production.
• Textile & Leather Processing: Acts as a chlorinating agent for wool to prevent felting shrinkage and is used in dye synthesis and leather tanning.
• Chemical Synthesis: Serves as a key raw material for producing sweeteners (sodium cyclamate), herbicides, flame retardants, and pharmaceutical intermediates.
• Electroplating & Metal Finishing: Utilized in electroplating baths for pH adjustment and as a mild pickling agent for metal surfaces.

Quality Control

Our Sulfamic Acid is manufactured under a stringent quality management system to ensure batch-to-batch consistency and high purity. We provide comprehensive analytical testing, with product specifications meeting or exceeding standard industrial and technical grade requirements. A Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is available for every batch upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent caking and degradation from atmospheric moisture. Keep away from strong bases and incompatible materials.
