Description

Methacrylic Acid-Sodium Hydrogen Sulfite Telomer, Sodium Salt is a specialized polymeric surfactant and dispersant derived from methacrylic acid. This compound is valued for its excellent scale inhibition and dispersing properties in aqueous systems, particularly against inorganic salts. It is primarily utilized in industrial water treatment applications, serving as a key additive in cooling water systems, boiler water treatment, and reverse osmosis membranes to prevent fouling and maintain operational efficiency.

Application

• Industrial Water Treatment: Acts as a highly effective scale inhibitor and dispersant in cooling water and boiler water systems.
• Reverse Osmosis (RO) Antiscalant: Prevents the precipitation and scaling of calcium carbonate, calcium sulfate, and barium sulfate on RO membranes.
• Detergent and Cleaning Formulations: Used as a builder and dispersing agent to enhance cleaning performance and prevent redeposition of soil.
• Pulp and Paper Industry: Employed as a dispersant in paper coating and bleaching processes to improve product quality and process efficiency.
• Textile Processing: Functions as a dye dispersant and anti-precipitant to ensure uniform dyeing and prevent scale in dye baths.
• Oilfield Chemicals: Applied in drilling fluids and production chemicals for scale control and as a clay stabilizer.

Quality Control

Our Methacrylic Acid-Sodium Hydrogen Sulfite Telomer, Sodium Salt is manufactured under a strict quality management system. Each batch undergoes rigorous testing to ensure consistent performance in scale inhibition and dispersion. Key parameters such as active content, molecular weight distribution, and pH are controlled. A Certificate of Analysis (COA) is provided with every shipment to guarantee compliance with agreed specifications.

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). This product is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which may affect product performance.
