Description

2-Propenoic Acid, Polymer With 2-Methyl-2-(1-Oxo-2-Propenyl)Amino-1-Propanesulfonic Acid, Sodium Salt is a high-performance, water-soluble anionic copolymer designed for demanding industrial applications. This specialized polymer is engineered to provide exceptional scale inhibition and dispersancy, particularly against calcium phosphate and other inorganic salts. It is a critical additive for water treatment, detergent formulations, and mineral processing industries where control of scale and deposits is paramount for operational efficiency and equipment longevity.

Application

• Industrial Water Treatment: Primary application as a highly effective scale inhibitor and dispersant in cooling water, boiler water, and reverse osmosis (RO) systems, specifically targeting calcium phosphate and carbonate scales.
• Detergent & Cleaning Formulations: Used as a builder and anti-redeposition agent in laundry detergents and industrial cleaners to enhance cleaning power and prevent soil from re-depositing onto fabrics or surfaces.
• Mineral Processing: Acts as a dispersant and anti-scalant in processes such as phosphate beneficiation and kaolin production to improve slurry stability and processing efficiency.
• Pulp & Paper Industry: Employed as a dispersant and deposit control agent to prevent pitch and stickies deposition, improving paper quality and machine runnability.
• Textile Auxiliaries: Functions as a leveling agent and dispersant in dyeing processes to ensure uniform color uptake and prevent dye agglomeration.
• Oilfield Chemicals: Utilized in drilling fluids and production chemicals for scale control and as a rheology modifier.
• Construction Chemicals: Added to cement admixtures and gypsum slurries as a superplasticizer and water reducer to improve workability and final strength.
• Personal Care: Can be used in select personal care products as a thickener and stabilizer due to its anionic polyelectrolyte nature.

Quality Control

Our production of AA/AMPS copolymer adheres to stringent quality management protocols to ensure batch-to-batch consistency and performance reliability. Each lot undergoes comprehensive analysis, including determination of active polymer content, residual monomer levels, molecular weight distribution, pH, and viscosity. Certificates of Analysis (COA) documenting these parameters are provided with every shipment. Our quality system is designed to meet the requirements of various industrial standards, and we can support compliance documentation for specific regulatory needs 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 product is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent moisture absorption, which may affect product performance and flow characteristics. Keep away from incompatible materials such as strong oxidizing agents.
