Description

2-Propenoic Acid, Polymer With 2-Hydroxy-3-(2-Propenyloxy)-1-Propanesulfonic Acid Monosodium Salt is a high-performance, water-soluble copolymer designed to deliver exceptional scale inhibition and dispersancy in demanding aqueous systems. This specialized polymer is engineered to address critical challenges in industrial water treatment by effectively controlling scale formation and particulate fouling. It is a vital component for industries requiring reliable and efficient water management solutions, particularly in cooling water systems, reverse osmosis membranes, and oilfield applications.

Application

• Industrial Water Treatment: Primary application as a highly effective antiscalant and dispersant in cooling towers, boilers, and closed-loop systems to prevent calcium carbonate, sulfate, and phosphate scales.
• Reverse Osmosis (RO) & Nanofiltration (NF): Critical for protecting sensitive membrane surfaces from scaling and colloidal fouling, enhancing water flux and extending membrane lifespan in desalination and purification plants.
• Oilfield Production: Used in squeeze treatments and continuous injection programs to control mineral scales in downhole formations, wellheads, and production equipment, ensuring optimal flow assurance.
• Detergent & Cleaning Formulations: Acts as a builder and dispersing agent in industrial and institutional cleaning products to prevent redeposition of soil and inhibit inorganic salt precipitation.
• Pulp & Paper Processing: Employed as a dispersant and deposit control agent to manage pitch, stickies, and scale in paper mill white water systems, improving runnability and product quality.
• Textile Processing: Utilized in dyeing and finishing baths to prevent precipitation of dyes and hard water salts, ensuring uniform color and fabric quality.
