Description

2-Butenedioic Acid (Z)-, Monomethyl Ester, Polymer With Ethenylbenzene And 2,5-Furandione, Sodium Salt is a specialized, water-soluble polymer derived from maleic acid, styrene, and maleic anhydride. This product matters as a versatile, anionic polyelectrolyte offering excellent dispersing, sequestering, and scale-inhibiting properties in aqueous systems. It is primarily needed by formulators in the water treatment, detergent, textile, and construction industries seeking high-performance additives for process control and product enhancement.

Application

• Water Treatment: Acts as a highly effective scale and corrosion inhibitor in cooling water, boiler water, and reverse osmosis systems.
• Detergent & Cleaning Formulations: Functions as a superior builder and dispersant, enhancing cleaning power by sequestering hardness ions and preventing soil redeposition.
• Textile Processing: Used as a dye dispersant and leveling agent, and for scale prevention in dyeing and finishing baths.
• Construction Chemicals: Serves as a plasticizer and water-reducing agent in cement and concrete admixtures to improve workability and strength.
• Paper & Pulp Industry: Employed as a dispersant for pigments and fillers, and as a retention aid in papermaking processes.
• Industrial Cleaning: Key component in formulations for metal cleaning, circuit board etching, and dairy/brewery cleaning due to its chelating power.
• Oilfield Chemicals: Utilized in drilling muds and production chemicals as a viscosity modifier and scale inhibitor.
• Personal Care: Can be used in select cosmetic and personal care products as a film former and stabilizer.
