Description

Phenol, Polymer With Formaldehyde, Sulfonated, Sodium Salts is a synthetic, water-soluble anionic polymer derived from phenol-formaldehyde chemistry. This specialized compound is valued for its excellent dispersing, sequestering, and scale-inhibiting properties in aqueous systems. It is primarily utilized in industrial water treatment, oilfield applications, and as a functional additive in construction and textile processing. The product is supplied as a hygroscopic solid and requires appropriate storage conditions to maintain its performance.

Application

• Industrial Water Treatment: Acts as a highly effective dispersant and antiscalant for cooling water, boiler water, and reverse osmosis systems.
• Oilfield Chemicals: Used in drilling muds and completion fluids for clay stabilization and as a fluid loss control additive.
• Construction Industry: Functions as a superplasticizer and water-reducing agent in concrete admixtures to improve workability.
• Textile Processing: Serves as a dye dispersant and leveling agent to ensure uniform color application.
• Paper & Pulp Manufacturing: Utilized as a retention aid and dispersant to improve paper quality and production efficiency.
• Ceramic & Clay Processing: Acts as a deflocculant to control slurry viscosity and improve casting properties.
