Description

Formaldehyde, Polymers With Sulfonated Phenol, Sodium Salts is a synthetic, water-soluble polymer derived from the condensation of formaldehyde with sulfonated phenol, subsequently neutralized to its sodium salt form. This specialized chemical is engineered to function as a highly effective dispersant and complexing agent, offering superior performance in demanding aqueous systems. It is a critical raw material for industries requiring advanced scale inhibition, sludge conditioning, and metal ion sequestration, such as water treatment, textile processing, and oilfield applications.

Application

• Industrial Water Treatment: Primary application as a high-performance scale and corrosion inhibitor in cooling towers, boilers, and reverse osmosis systems.
• Oilfield Chemicals: Used in drilling muds and production chemicals for its dispersing and fluid-loss control properties.
• Textile & Dyeing Auxiliary: Acts as a dispersing agent for dyes and pigments, improving color uniformity and process efficiency.
• Detergent & Cleaning Formulations: Serves as a builder and anti-redeposition agent to enhance cleaning power and prevent soil from re-adhering to fabrics.
• Paper & Pulp Industry: Utilized as a dispersant and retention aid in papermaking processes.
• Ceramic & Construction: Functions as a plasticizer and water reducer in cement and ceramic slurries.
• Metal Surface Treatment: Employed in cleaning and pickling baths to complex metal ions and control precipitation.
