Description

Poly(Acrylic Acid) is a high molecular weight, synthetic polymer of acrylic acid. This versatile water-soluble polymer is valued for its exceptional chelating, dispersing, and scale-inhibiting properties, making it a critical performance additive in numerous industrial processes. It is essential for manufacturers in water treatment, detergent formulation, mineral processing, and personal care industries seeking to improve efficiency and product performance.

Application

• Water Treatment: Acts as a highly effective scale inhibitor and dispersant for calcium carbonate and phosphate scales in cooling water, boiler water, and reverse osmosis systems.
• Detergents & Cleaners: Functions as a builder and anti-redeposition agent in laundry and dishwashing detergents, enhancing cleaning power and preventing soil from re-adhering to fabrics.
• Mineral Processing: Used as a dispersant and grinding aid to improve efficiency and throughput in the processing of minerals like calcium carbonate and kaolin.
• Personal Care: Serves as a thickening agent, stabilizer, and film-former in products such as hair gels, creams, and lotions.
• Textile Industry: Employed as a dye dispersant and anti-precipitant to ensure uniform color application and prevent dye agglomeration.
• Paper Manufacturing: Utilized as a retention aid and dispersant to improve paper strength, filler retention, and production efficiency.
• Superabsorbent Polymers (SAP): A key raw material in the production of superabsorbent polymers used in hygiene products like diapers and sanitary napkins.

Quality Control

Our Poly(Acrylic Acid) is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistency and compliance with relevant industry standards. Certificates of Analysis (COA) detailing key parameters such as molecular weight, solids content, pH, and viscosity are provided to guarantee reliable performance in your application.

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); ensure containers are sealed immediately after use to prevent caking or viscosity changes due to moisture absorption.
