Description

2-Propenoic Acid, Polymer With Methyl 2-Propenoate, Sodium Salt is a water-soluble anionic copolymer of acrylic acid and methyl acrylate, widely utilized as a versatile dispersant and scale inhibitor. This polymer is valued for its ability to control mineral scale formation and suspend particulate matter in aqueous systems, enhancing process efficiency and equipment longevity. It is a critical component for water treatment, detergent formulation, and mineral processing industries seeking reliable performance under demanding conditions.

Application

• Industrial Water Treatment: Acts as a highly effective dispersant and antiscalant in cooling water, boiler water, and reverse osmosis systems to prevent calcium carbonate and sulfate scales.
• Detergent & Cleaner Formulations: Serves as a builder and anti-redeposition agent in laundry detergents and industrial cleaners, enhancing soil suspension and preventing particle re-deposition on fabrics.
• Mineral Processing: Used as a dispersant in pigment slurries, ceramic processing, and ore beneficiation to improve slurry stability and flow properties.
• Textile & Paper Industries: Functions as a processing aid and dispersant for dyes, coatings, and fillers, ensuring uniform application and product quality.
• Construction Chemicals: Incorporated into cement admixtures and gypsum plaster to control water demand and improve workability and final strength.

Quality Control

Our production of 2-Propenoic Acid, Polymer With Methyl 2-Propenoate, Sodium Salt adheres to stringent quality management protocols. Each batch is characterized for critical parameters including solid content, viscosity, pH, and residual monomer levels to ensure consistent performance. Certificates of Analysis (COA) documenting these specifications are provided with every shipment to guarantee traceability and compliance with your application requirements.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive) and must be stored in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep the container tightly sealed when not in use to prevent moisture absorption and caking.
