Description

(1,1'-Biphenyl)Sulfonic Acid, 4-Hydroxy-, Polymer With Formaldehyde, Sodium Salt is a synthetic, water-soluble polymeric dispersant and complexing agent. This compound is valued for its ability to control scale formation and inhibit precipitation of inorganic salts in aqueous systems. It is primarily needed by industrial water treatment, detergent formulation, and textile processing operations seeking high-performance antiscalants and dispersants.

Application

• Industrial Water Treatment: Acts as a highly effective antiscalant and dispersant in cooling water, boiler water, and reverse osmosis (RO) systems to control calcium carbonate, calcium sulfate, and barium sulfate scales.
• Detergent & Cleaning Formulations: Serves as a builder and dispersant in powder and liquid detergents, enhancing cleaning efficiency by sequestering hardness ions and preventing soil redeposition.
• Textile Processing: Used as a dispersing agent in dyeing processes to improve color uniformity and prevent agglomeration of dyes.
• Pulp & Paper Industry: Functions as a dispersant and scale inhibitor in process water to improve operational efficiency and product quality.
• Oilfield Chemicals: Employed in drilling fluids and production chemicals to prevent mineral scale deposition in wells and surface equipment.
• Ceramic & Construction: Acts as a grinding aid and plasticizer in ceramic slips and cement admixtures to improve particle dispersion and workability.
