Description

Styrene Homopolymer, Sulfonated, Sodium Salt is a synthetic, water-soluble polyelectrolyte derived from polystyrene. This anionic polymer is valued for its exceptional dispersing, sequestering, and viscosity-modifying properties in aqueous systems. It serves as a critical performance additive in diverse industrial sectors including water treatment, construction, textiles, and personal care, where control over ionic interactions and particle stability is required.

Application

• Water Treatment: Acts as a highly effective scale inhibitor and dispersant for calcium carbonate and other mineral salts in cooling water, boiler water, and reverse osmosis systems.
• Construction Chemicals: Used as a superplasticizer and grinding aid in cement and concrete formulations to improve workability, reduce water content, and enhance final strength.
• Textile & Leather Processing: Functions as a dye dispersant and leveling agent, and as a tanning auxiliary to improve the penetration and fixation of tanning agents.
• Personal Care & Detergents: Employed as a thickening agent, stabilizer, and anti-redeposition agent in shampoos, liquid soaps, and laundry detergents.
• Paper & Pulp Industry: Serves as a retention aid, drainage aid, and dispersant to improve paper quality and manufacturing efficiency.
• Ceramics & Paints: Utilized as a deflocculant in ceramic slips and as a pigment dispersant in water-based paints and coatings to ensure stable suspensions.
• Oilfield Chemicals: Applied as a fluid loss additive and clay stabilizer in drilling muds and completion fluids.
• Industrial Cleaning: Enhances the cleaning efficacy of industrial formulations by preventing redeposition of soil and scale on surfaces.

Quality Control

Our Styrene Homopolymer, Sulfonated, Sodium Salt is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure consistent performance, including assessment of sulfonation degree, molecular weight distribution, ionic content, and purity. Certificates of Analysis (COA) documenting all critical parameters are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which may affect product performance.
