Description

Butanedioic Acid, Methylene-, Polymer With Ethyl 2-Propenoate, Ammonium Salt is a synthetic, water-soluble polymer widely utilized as a high-performance dispersant and scale inhibitor. This compound is valued for its exceptional ability to control mineral scale formation and stabilize particulate matter in aqueous systems. It is a critical additive for industries requiring efficient water treatment and process stabilization, such as industrial cleaning, pulp & paper manufacturing, and oilfield production.

Application

• Industrial Water Treatment: Primary application as a highly effective dispersant and antiscalant in cooling water, boiler water, and reverse osmosis systems to prevent calcium carbonate, sulfate, and phosphate scales.
• Detergent & Cleaning Formulations: Acts as a builder and dispersing agent in industrial and institutional cleaning products, enhancing soil suspension and preventing redeposition.
• Pulp & Paper Processing: Used to control pitch and stickies, and as a dispersant for pigments and fillers like calcium carbonate and kaolin clay to improve paper quality and machine runnability.
• Oilfield Chemicals: Employed in drilling fluids, completion brines, and production chemicals to inhibit scale deposition in downhole and surface equipment, protecting asset integrity.
• Textile Processing: Serves as a dispersant in dyeing and printing processes to ensure uniform color distribution and prevent agglomeration of dyestuffs.
• Ceramic & Clay Processing: Functions as a deflocculant to improve the rheology and workability of ceramic slips and clay suspensions.

Quality Control

Our production of Butanedioic Acid, Methylene-, Polymer With Ethyl 2-Propenoate, Ammonium Salt adheres to stringent quality management protocols to ensure batch-to-batch consistency and performance reliability. Each lot is tested against key parameters including solid content, pH, viscosity, and functional performance in standard dispersion tests. Certificates of Analysis (COA) documenting these results are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); keep container tightly sealed when not in use to prevent absorption of atmospheric moisture which may affect product performance.
