Description

2-Butenedioic Acid (Z)-, Disodium Salt, Polymer With Ethenylbenzene is a synthetic, water-soluble polyelectrolyte copolymer derived from maleic acid and styrene. This compound is valued for its excellent chelating, dispersing, and scale inhibition 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 ions 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, enhancing cleaning efficiency by sequestering calcium and magnesium ions.
• Pulp & Paper Processing: Used as a dispersant for pigments and fillers, and to control pitch and scale deposition.
• Textile Industry: Serves as a dye dispersant and anti-redeposition agent in washing processes.
• Oilfield Chemicals: Employed in drilling fluids and production chemicals for scale control and as a clay stabilizer.
• Construction Chemicals: Added to cement and concrete admixtures as a water reducer and set retarder.
