Description

2,5-Furandione, Telomer With Ethenylbenzene And (1-Methylethyl)Benzene, Sodium Salt is a specialized polymeric surfactant and dispersant derived from maleic anhydride (2,5-Furandione). This compound is valued for its excellent surface-active properties and ability to control scale and deposit formation in aqueous systems. It is primarily utilized in industrial water treatment, detergent formulations, and as a processing aid in polymer and pigment production. The sodium salt form ensures good solubility and handling characteristics for efficient downstream application.

Application

• Industrial Water Treatment: Acts as a highly effective scale and corrosion inhibitor in cooling water systems, boilers, and reverse osmosis membranes.
• Detergent & Cleaner Formulations: Serves as a builder and dispersant in laundry detergents, dishwashing liquids, and industrial cleaners to enhance soil suspension and prevent redeposition.
• Pigment & Filler Dispersion: Used as a grinding aid and dispersing agent for inorganic pigments, fillers, and ceramics to achieve stable, agglomerate-free suspensions.
• Polymerization Aid: Functions as an emulsifier, surfactant, or particle size control agent in emulsion and suspension polymerization processes.
• Oilfield Chemicals: Employed in drilling muds and production chemicals for scale inhibition and fluid dispersion.
• Textile & Leather Processing: Aids in dye leveling, tanning processes, and as a dispersant for textile auxiliaries.
• Paper & Pulp Industry: Used in paper coating formulations and as a dispersant to control pitch and improve paper quality.
• Construction Chemicals: Acts as a plasticizer and water-reducing agent in concrete admixtures and cement grinding aids.
