Description

Naphthalenesulfonic Acid, Methyl-, Sodium Salt, Polymer With Formaldehyde is a synthetic, water-soluble anionic polymer derived from naphthalene. This compound is valued for its powerful dispersing and complexing properties, which are critical for controlling particle agglomeration and scale formation in industrial processes. It is primarily needed by manufacturers in the construction, textile, and water treatment industries, where it functions as a highly effective superplasticizer, dye dispersant, and antiscalant.

Application

• As a high-range water reducer (superplasticizer) in concrete and cement formulations to improve workability and strength.
• As a dispersing agent for pigments and dyes in the textile and paint industries.
• As an antiscalant and dispersant in industrial water treatment and cooling tower systems.
• In the formulation of agricultural chemicals to enhance the stability and dispersion of active ingredients.
• As a grinding aid in the production of minerals and ceramics.
• In oilfield applications as a mud thinner and dispersant for drilling fluids.

Quality Control

Our Naphthalenesulfonic Acid, Methyl-, Sodium Salt, Polymer With Formaldehyde is manufactured under a strict quality management system. Each batch undergoes rigorous testing for key parameters such as sulfonation degree, molecular weight distribution, and dispersing performance to ensure consistency and efficacy for your specific application. Certificates of Analysis (COA) documenting these specifications are available upon request.

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); ensure containers are kept sealed to prevent absorption of atmospheric moisture, which can affect product performance.
