Description

2-Butenedioic Acid (2Z)-, Polymer With 2-Propenoic Acid, Sodium Salt is a water-soluble polycarboxylate copolymer, commonly known as a polycarboxylate ether (PCE) or a maleic acid/acrylic acid copolymer sodium salt. This polymer is engineered to deliver superior performance as a dispersant and scale inhibitor in demanding aqueous systems. It is a critical raw material for formulators in the water treatment, construction chemicals, and detergent industries who require reliable, high-purity functional polymers to ensure product consistency and efficacy. The product, identified by CAS No. 60472-42-6, is supplied as a hygroscopic solid, necessitating careful handling and storage.

Application

This sodium polycarboxylate copolymer is a versatile functional polymer with key applications across several industrial sectors:

• Water Treatment: Acts as a highly effective antiscalant and dispersant in cooling water, boiler water, and reverse osmosis (RO) systems to control calcium carbonate, sulfate, and phosphate scales.
• Construction Chemicals: Serves as a powerful superplasticizer and water-reducing agent in concrete and cement formulations, improving workability and final strength.
• Detergents & Cleaners: Functions as a builder and dispersant in industrial and institutional cleaning formulations, enhancing soil suspension and preventing redeposition.
• Textile & Dyeing: Used as a dispersing agent for pigments and dyes, ensuring uniform color application and preventing agglomeration.
• Paper & Pulp Industry: Employed as a retention aid and dispersant to improve paper quality and manufacturing efficiency.
• Personal Care: Can be utilized as a viscosity modifier and stabilizer in certain cosmetic and personal care products.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive) and must be stored in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep the container tightly sealed when not in use to prevent moisture absorption and caking. Store away from incompatible materials such as strong oxidizing agents.
