Description

Polycarboxylic Acid, Sodium Salt is a versatile, water-soluble polymer widely used as a high-performance dispersant and scale inhibitor. Its primary value lies in its exceptional ability to control crystallization and prevent the precipitation of inorganic salts, such as calcium carbonate and calcium sulfate, in aqueous systems. This product is essential for industries requiring efficient water treatment, including industrial cleaning formulations, textile processing, and detergent manufacturing.

Application

• Water Treatment: Acts as a highly effective scale and corrosion inhibitor in cooling water systems, boilers, and reverse osmosis membranes.
• Detergent & Cleaner Builders: Serves as a superior builder and dispersant in laundry detergents, dishwashing liquids, and industrial cleaners, enhancing soil suspension and preventing redeposition.
• Textile Processing: Used as a dispersing agent in dyeing and printing processes to ensure uniform color distribution and prevent spotting.
• Pulp & Paper Industry: Functions as a dispersant for pigments and fillers like calcium carbonate, improving paper quality and production efficiency.
• Construction Chemicals: Employed as a superplasticizer and water-reducing agent in concrete admixtures to improve workability and strength.
• Oilfield Chemicals: Utilized in drilling fluids and production chemicals to control scale formation and improve fluid performance.
• Industrial Cleaning: Key component in formulations for cleaning heat exchangers, pipelines, and other industrial equipment prone to mineral scale.

Quality Control

Our Polycarboxylic Acid, Sodium Salt is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent performance and compliance with relevant industry standards. A comprehensive Certificate of Analysis (COA), detailing parameters such as assay, pH, viscosity, and residual monomer content, is provided with every shipment to guarantee supply reliability and product integrity.

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