Description

2-Propenoic Acid, 2-Hydroxy-, Monosodium Salt, Homopolymer is a high-purity, synthetic polymer derived from acrylic acid, widely recognized for its exceptional water solubility and chelating properties. This versatile material is crucial for controlling scale and dispersing particulates in demanding aqueous systems. It is primarily utilized by the water treatment, detergent, and textile processing industries where effective mineral ion sequestration and anti-redeposition are required for optimal process performance and product quality.

Application

• Industrial Water Treatment: Acts as a highly effective scale inhibitor and dispersant for calcium carbonate, sulfate, and phosphate in cooling towers, boilers, and reverse osmosis systems.
• Detergent & Cleaner Formulations: Functions as a superior builder and anti-redeposition agent in laundry and dishwashing detergents, enhancing cleaning power and preventing soil from re-adhering to fabrics.
• Textile Processing: Used as a dispersing agent in dyeing and printing processes to ensure uniform color application and prevent spotting.
• Pulp & Paper Manufacturing: Serves as a dispersant and chelant in pulp bleaching and paper coating processes to improve brightness and process efficiency.
• Oilfield Applications: Employed in drilling fluids and production chemicals to control scale formation in downhole and topside equipment.
• Personal Care Products: Incorporated into formulations such as shampoos and body washes for its sequestering and viscosity-modifying properties.
