Description

Acrylic acid (CAS 79-10-7 ), also known as vinylformic acid and commonly abbreviated as AA, is a reactive monomer used as the foundational building block for polyacrylate synthesis across polymer and specialty chemical manufacturing. Its ability to undergo controlled polymerization or co-polymerization makes it a primary raw material for producing superabsorbent polymers, dispersants, and coating resins. AA is the primary feedstock for superabsorbent polymers used in hygiene products. These applications include disposable diapers and adult incontinence articles. In water treatment and detergent formulations, it is polymerized into dispersants and scale inhibitors that prevent mineral deposit buildup in industrial systems. Acrylic acid co-polymers form the backbone of pressure-sensitive adhesives, surface coatings, and textile sizing agents where controlled adhesion and film formation are required. These materials are essential for modern industrial manufacturing. Personal care formulators use polyacrylate thickeners derived from AA as rheology modifiers in gels, creams, and hair styling products. This versatility ensures its widespread use in the cosmetic and pharmaceutical sectors globally. Acrylic acid is supplied as a stabilized liquid, typically with hydroquinone monomethyl ether added to inhibit premature polymerization during storage and transport. This ensures the material remains stable for industrial use. Standard commercial grades include glacial and technical grades, with purity levels commonly at 99%+ for polymer-grade applications. These products meet rigorous industrial specifications for high-performance chemical synthesis. Bulk supply is available in drums, ISO tanks, and flexi-tanks depending on volume requirements. Our logistics network ensures safe and efficient delivery of this essential monomer to your facility according to your specific needs. Contact us for supply of Acrylic acid Request Quote
