Description

Poly(Acrylic Acid) Partial Na Salt is a versatile, water-soluble polymer derived from acrylic acid, partially neutralized with sodium hydroxide. This product is valued for its exceptional chelating, dispersing, and scale-inhibiting properties in aqueous systems. It is a critical component for formulators and process engineers in industries such as water treatment, detergents, and personal care, where controlling mineral scale and improving cleaning efficiency are paramount.

Application

• Water Treatment: Acts as a highly effective scale inhibitor and dispersant for calcium carbonate and other mineral salts in cooling water, boiler water, and reverse osmosis systems.
• Detergent & Cleaner Formulations: Enhances the performance of laundry and dishwashing detergents by sequestering hardness ions (Ca²⁺, Mg²⁺), preventing soil redeposition, and improving overall cleaning efficacy.
• Personal Care Products: Used as a thickening agent, stabilizer, and sequestrant in shampoos, body washes, and other cosmetic formulations.
• Industrial Cleaning: Serves as a key ingredient in industrial and institutional (I&I) cleaners for its superior dispersing and anti-scaling properties.
• Textile & Paper Processing: Functions as a dispersant for pigments and fillers and as a processing aid to prevent scale buildup on equipment.
• Construction Chemicals: Incorporated into cement and concrete admixtures to improve workability and fluidity by dispersing particles.

Quality Control

Our Poly(Acrylic Acid) Partial Na Salt is manufactured under a stringent quality management system. Each batch undergoes rigorous testing to ensure consistent performance, including analysis of molecular weight distribution, degree of neutralization, solids content, and residual monomer levels. Certificates of Analysis (COA) are provided with every shipment to guarantee compliance with your specifications and industry standards.

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); keep the container tightly sealed when not in use to prevent caking or degradation due to moisture absorption.
