Description

Naphthalenesulfonic Acids, Polymers With Formaldehyde, Sodium Salts is a synthetic, water-soluble anionic polymer derived from naphthalene. This compound is valued as a highly effective dispersant and plasticizer, crucial for controlling particle agglomeration and improving workability in various industrial formulations. It is primarily needed by manufacturers in the construction, textile, and agrochemical industries for its ability to enhance product performance and process efficiency.

Application

• Concrete Admixtures: Acts as a superplasticizer and water-reducing agent to improve the workability and strength of concrete mixes.
• Ceramic & Pigment Dispersion: Used as a grinding aid and dispersant to stabilize suspensions and prevent settling of solid particles.
• Textile & Leather Auxiliaries: Serves as a leveling agent and dye dispersant to ensure uniform color application.
• Agrochemical Formulations: Enhances the stability and dispersibility of pesticides and herbicides in water.
• Oilfield Chemicals: Functions as a fluid loss additive and dispersant in drilling mud formulations.
• Industrial Cleaners: Used in detergent formulations to prevent redeposition of soil and improve cleaning efficacy.
• Paper Manufacturing: Acts as a retention aid and dispersant in pulp processing.
