Description

Ethylene/Sodium Acrylate Copolymer is a synthetic, water-soluble polymer formed from the copolymerization of ethylene and sodium acrylate monomers. This material is valued for its exceptional thickening, suspending, and water-absorbing properties, making it a key performance additive in numerous industrial formulations. It is primarily utilized by manufacturers in the personal care, water treatment, textile, and coatings industries seeking to modify rheology and enhance product stability.

Application

• Personal Care & Cosmetics: Acts as a primary thickener, stabilizer, and film-forming agent in shampoos, body washes, lotions, and creams.
• Water Treatment: Used as a flocculant and dispersant to aid in the clarification process and control scale formation in industrial water systems.
• Textile & Fiber Processing: Serves as a sizing agent, thickener for printing pastes, and finishing agent to improve fabric hand feel and performance.
• Paints & Coatings: Functions as a rheology modifier and thickener in latex paints and industrial coatings to control viscosity and prevent sagging.
• Detergents & Cleaners: Enhances the viscosity and stability of liquid soaps, dishwashing liquids, and hard surface cleaners.
• Adhesives & Sealants: Utilized as a thickening and water-retention agent in various adhesive formulations.

Quality Control

Our Ethylene/Sodium Acrylate Copolymer is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent performance, including assessment of viscosity, solids content, pH, and residual monomers. Certificates of Analysis (COA) documenting these parameters are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. This product is hygroscopic (moisture-sensitive). Store 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.
