Description

2-Naphthalenesulfonic Acid, Sodium Salt, Polymer With Formaldehyde is a synthetic, water-soluble anionic polymer derived from naphthalene sulfonate. This compound is valued for its powerful dispersing and plasticizing properties, which are critical for controlling the rheology and setting characteristics of various industrial mixtures. It is primarily needed by manufacturers in the construction, textile, and ceramics industries, where it acts as a high-efficiency superplasticizer and grinding aid.

Application

As a superplasticizer and water-reducing agent in concrete and cement formulations to improve workability and strength.
As a dispersing agent in the production of pigments, dyes, and ceramic slurries.
As a grinding aid in the manufacture of cement to increase mill output and efficiency.
As a leveling and retarding agent in gypsum and plaster-based products.
As a tanning auxiliary and dye dispersant in the leather and textile industries.
As a fluid loss reducer in oil well drilling mud formulations.

Quality Control

Our 2-Naphthalenesulfonic Acid, Sodium Salt, Polymer With Formaldehyde is manufactured under a strict quality management system. Each batch undergoes rigorous testing for key parameters such as sulfonate content, degree of polymerization, and pH to ensure consistent performance as a dispersant. 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); the container must be kept tightly sealed to prevent caking and degradation from atmospheric moisture.
