Description

Butanedioic Acid, Methylene-, Polymer With 1,3-Butadiene, Diethenylbenzene And Ethenylbenzene, Sodium Salt is a specialized anionic polymeric surfactant derived from succinic acid. This compound matters for its unique combination of surface-active properties, including excellent dispersing, emulsifying, and sequestering capabilities. It is primarily needed by manufacturers in the construction, coatings, textile, and personal care industries for formulating high-performance additives and processing aids.

Application

• Construction Chemicals: Acts as a highly effective dispersant and plasticizer in cement admixtures and concrete formulations to improve workability and reduce water content.
• Industrial Coatings & Paints: Used as a pigment grinding aid and stabilizer in water-based coatings to prevent settling and ensure consistent color and gloss.
• Textile Processing: Serves as a leveling agent and dye dispersant in dye baths to promote uniform color uptake and fastness on synthetic fibers.
• Detergents & Cleaners: Functions as a builder and anti-redeposition agent in liquid and powder detergents to enhance soil suspension and cleaning efficiency.
• Personal Care Products: Employed as a thickener and stabilizer in shampoos, body washes, and creams to modify rheology and improve product feel.
• Oilfield Chemicals: Utilized in drilling mud formulations as a rheology modifier and fluid loss control additive.
• Paper Manufacturing: Applied as a retention and drainage aid in the wet-end process to improve paper sheet formation and machine runnability.
• Agricultural Formulations: Acts as a compatibilizer and dispersant in pesticide and herbicide suspensions and emulsions.

Quality Control

Our Butanedioic Acid, Methylene-, Polymer is manufactured under a strict quality management system. Every batch undergoes rigorous testing to ensure consistent performance and compliance with relevant industrial specifications. Certificates of Analysis (COA) documenting key parameters such as solid content, pH, viscosity, and ionic character are available upon request to support your quality assurance protocols.

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/59-77°F). Keep the container tightly sealed when not in use to prevent moisture absorption and caking.
