Description

2-Propenoic Acid, Methyl Ester, Homopolymer, Sodium Salt is a water-soluble anionic polymer derived from poly(methyl acrylate). This versatile chemical is valued for its excellent thickening, dispersing, and stabilizing properties in aqueous systems. It is a critical raw material for formulators in industries such as water treatment, construction, and personal care, where consistent rheology control and product performance are paramount.

Application

• Water Treatment: Acts as a highly effective scale inhibitor and dispersant in cooling water, boiler water, and reverse osmosis systems.
• Construction Chemicals: Used as a superplasticizer and rheology modifier in cement, mortar, and gypsum-based products to improve workability and reduce water content.
• Personal Care & Cosmetics: Functions as a thickener, emulsifier, and film-forming agent in hair gels, creams, lotions, and other aqueous cosmetic formulations.
• Paints & Coatings: Serves as a rheology modifier and pigment dispersant in water-based paints, improving application properties and stability.
• Textile & Leather Processing: Employed as a sizing agent, thickener for printing pastes, and auxiliary in leather finishing for improved handle and quality.
• Detergents & Cleaners: Enhances the viscosity and suspension properties of liquid soaps, hard surface cleaners, and industrial detergents.
• Paper Manufacturing: Used as a retention aid, drainage aid, and coating additive to improve paper strength and printability.
• Adhesives & Sealants: Acts as a thickening and binding agent in water-based adhesive formulations.
