Description

Isobutylene/Sodium Maleate Copolymer CAS NO 55031-88-4 is a synthetic, water-soluble polymer derived from the copolymerization of isobutylene and maleic anhydride, subsequently neutralized to its sodium salt form. This versatile polymer is valued for its excellent dispersing, chelating, and scale-inhibiting properties in aqueous systems. It is primarily utilized in industrial water treatment, detergent formulations, and as a processing aid in various manufacturing sectors where control of mineral deposits and particulate matter is critical.

Application

• Industrial Water Treatment: Acts as a highly effective scale and corrosion inhibitor in cooling towers, boilers, and reverse osmosis systems.
• Detergent & Cleaning Formulations: Functions as a builder and dispersant to enhance cleaning efficiency by sequestering hard water ions and preventing soil redeposition.
• Pulp & Paper Processing: Used as a dispersant for pigments and fillers, and to control pitch and stickies.
• Textile Industry: Serves as a dye dispersant and anti-redeposition agent in scouring and dyeing processes.
• Oilfield Chemicals: Employed in drilling fluids and production chemicals for scale inhibition and as a clay stabilizer.
• Construction Chemicals: Acts as a superplasticizer and water-reducing agent in concrete admixtures.
• Personal Care Products: Used in select formulations as a thickener, stabilizer, or film-forming agent.

Quality Control

Our Isobutylene/Sodium Maleate Copolymer is manufactured under a stringent quality management system. Each batch undergoes rigorous testing to ensure consistent performance, including analysis of active content, viscosity, pH, and residual monomers. A Certificate of Analysis (COA) documenting these parameters is provided with every shipment to guarantee compliance with your specifications and industry standards.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive). Store 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.
