Description

1-Naphthalenesulfonic Acid, Calcium Salt, Polymer With Formaldehyde is a synthetic polymeric chemical compound widely used as a high-performance dispersant and scale inhibitor. This product is valued for its ability to effectively control crystal growth and prevent the precipitation of inorganic salts in aqueous systems. It is primarily needed by the water treatment, textile processing, and construction chemical industries for applications requiring superior sequestration and dispersion properties.

Application

• Industrial Water Treatment: Acts as a highly effective scale inhibitor and dispersant in cooling water, boiler water, and reverse osmosis systems to control calcium carbonate, calcium sulfate, and barium sulfate scaling.
• Construction Chemicals: Used as a plasticizer and water-reducing agent in concrete admixtures to improve workability and final strength.
• Textile Processing: Serves as a dispersing agent in dyeing processes to ensure uniform color distribution and prevent dye agglomeration.
• Pigment & Filler Dispersion: Enhances the stability and homogeneity of pigment slurries and filler suspensions in paints, coatings, and paper manufacturing.
• Oilfield Chemicals: Employed in drilling muds and production chemicals to inhibit scale formation in downhole and surface equipment.
• Detergent Formulations: Functions as a builder and anti-redeposition agent in industrial and institutional cleaning products.

Quality Control

Our 1-Naphthalenesulfonic Acid, Calcium Salt, Polymer With Formaldehyde is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure consistent performance and meets the specifications required for industrial applications. A Certificate of Analysis (COA) detailing key parameters such as active content, pH, and viscosity is provided with each shipment and is available 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). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which may affect product performance.
