Description

2-Butenedioic Acid, Monoethyl Ester, Polymer With Ethenyl Acetate And Sodium Ethenesulfonate is a specialized water-soluble polymer designed to deliver superior performance as a dispersant and scale inhibitor. This copolymer is engineered to provide excellent chelation and threshold inhibition properties, making it a critical component in water treatment and industrial process formulations. It is essential for industries requiring high-efficiency antiscalants and dispersants for challenging aqueous systems.

Application

• Industrial Water Treatment: Primary application as a high-performance antiscalant and dispersant in cooling water, boiler water, and reverse osmosis (RO) systems to control calcium carbonate, sulfate, and phosphate scales.
• Oilfield Chemicals: Used in drilling fluids and production chemicals to inhibit scale formation in downhole and topside equipment, enhancing operational efficiency.
• Detergent & Cleaning Formulations: Acts as a builder and dispersant in industrial and institutional cleaning products to prevent redeposition of soil and improve cleaning efficacy.
• Textile & Dyeing Auxiliaries: Serves as a dispersing agent for pigments and dyes, ensuring uniform color distribution and preventing agglomeration.
• Pulp & Paper Processing: Utilized as a deposit control agent and dispersant to manage pitch and stickies, improving paper quality and mill runnability.
• Construction Chemicals: Incorporated into concrete admixtures as a plasticizer or water-reducing agent to improve workability and final strength.

Quality Control

Our production of this terpolymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Each lot is tested against key parameters including solid content, viscosity, pH, and functional performance in standard scale inhibition tests. Certificates of Analysis (COA) documenting these specifications 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, 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 moisture absorption and caking.
