Description

Formaldehyde, Polymers With Sulfonated 1,1-Oxybismethylbenzene, Sodium Salts is a synthetic, water-soluble polyelectrolyte derived from formaldehyde and a sulfonated aromatic compound. This specialized polymer is valued for its strong anionic character and dispersing properties in aqueous systems. It is primarily utilized in industrial water treatment, construction materials, and as a functional additive in various chemical processes where charge stabilization and particle dispersion are critical.

Application

• Water Treatment: Acts as a highly effective dispersant and anti-scalant agent in cooling water, boiler water, and reverse osmosis systems.
• Construction Industry: Used as a superplasticizer and grinding aid in cement and concrete formulations to improve workability and reduce water content.
• Ceramics & Pigments: Serves as a powerful dispersant for inorganic particles in ceramic slips, glazes, and pigment suspensions.
• Oilfield Chemicals: Employed in drilling mud formulations and as a scale inhibitor in oil and gas production to prevent mineral deposits.
• Paper & Pulp: Functions as a retention aid and dispersant in paper coating and filler applications.
• Textile Processing: Used in dyeing and printing processes to improve color dispersion and uniformity.
• Detergent Formulations: Incorporated as a builder and anti-redeposition agent in industrial and institutional cleaning products.
• Industrial Cleaning: Acts as a dispersing agent for inorganic soils and scale in acid and alkaline cleaning formulations.
