Polyacrylate Product Description (CAS# 9003-01-4)

Polyacrylate—also known as polyacrylic acid (PAA)—is chemically defined as a homopolymer of acrylic acid. It has the molecular formula (C₃H₄O₂)n and a monomer molecular weight of 72.06. At room temperature, it appears as a colorless to pale yellow liquid and has a glass transition temperature of 106°C. It is highly water-soluble and capable of forming stable compounds with metal ions (such as calcium and magnesium), effectively dispersing calcium carbonate and calcium hydroxide in water. Industrially, polyacrylate is produced via the free-radical polymerization of acrylic acid monomers; grades intended for water treatment typically have a molecular weight ranging from 2,000 to 5,000. Thanks to its excellent dispersing, scale-inhibiting, and chelating properties, polyacrylate is widely used across various sectors, including water treatment, textiles, papermaking, coatings, and adhesives.

Applications of Polyacrylate Products (CAS# 9003-01-4)

Polyacrylate is an important functional polymer material widely used across various industries, including water treatment, textiles, papermaking, coatings, adhesives, and personal care products.

In the field of water treatment, polyacrylate serves as a scale inhibitor and dispersant for circulating cooling water systems. It prevents the precipitation of salts—such as calcium carbonate and calcium sulfate—by dispersing their microcrystals or suspended particles in the water, thereby inhibiting scale formation. In the textile industry, polyacrylate is utilized in sizing, printing, and finishing processes; it imparts stiffness and improves the hand-feel of the treated fabrics. It also functions as a binder for non-woven fabrics and flocked products. In the papermaking industry, polyacrylate acts as a dispersant and strengthening agent for paper. In the coatings industry, it serves as a film-forming agent and dispersant for water-based coatings. In the adhesive sector, polyacrylate’s adhesive properties allow it to be used in pressure-sensitive and heat-sensitive adhesives. In the personal care and household chemical industry, it is used as a thickener and stabilizer. Additionally, polyacrylate finds extensive application in industries such as ceramics and textile printing and dyeing.
