Description

Polymerofstyrene,Acrylicacidandsodium2-Methyl-2-Propene-1-Sulphonate CAS NO 196801-15-7 is a high-performance, water-soluble copolymer designed for demanding industrial applications. This specialized polymer offers exceptional dispersing, scale inhibition, and chelating properties, making it a critical component in water treatment and process chemistry. It is primarily utilized by industries requiring advanced antiscalants and dispersants for high-temperature and high-hardness aqueous systems.

Application

• Industrial Water Treatment: As a highly effective antiscalant and dispersant in cooling water, boiler water, and reverse osmosis (RO) systems, particularly effective against calcium carbonate, calcium sulfate, and barium sulfate scales.
• Oilfield Chemicals: Used in drilling fluids, completion fluids, and production chemicals for scale inhibition and clay dispersion to enhance oil recovery and protect downhole equipment.
• Detergent & Cleaning Formulations: Acts as a builder and dispersing agent in industrial and institutional cleaning products to prevent redeposition of soil and improve cleaning efficiency.
• Pulp & Paper Processing: Serves as a dispersant and deposit control agent to prevent pitch and stickies deposition, improving paper quality and mill runnability.
• Textile & Dyeing Auxiliary: Functions as a leveling agent and dispersant for dyes and pigments, ensuring uniform color application and preventing agglomeration.
• Construction & Cement Additives: Employed as a superplasticizer and grinding aid in cement and concrete admixtures to improve workability and reduce water content.
