Description

2-Propenoic Acid, Polymer With 2-Methyl-2-(1-Oxo-2-Propenyl)Amino-1-Propanesulfonic Acid Monosodium Salt And Sodium Phosphinite is a high-performance, water-soluble copolymer designed for demanding industrial applications. This specialized polymer combines acrylic acid with sulfonic acid and phosphinite functionalities, offering exceptional scale inhibition, dispersancy, and chelating properties in aqueous systems. It is a critical additive for industries requiring robust water treatment and process control, where it effectively prevents mineral scale deposition and stabilizes suspended particles. The product is supplied as a hygroscopic solid, necessitating proper storage to maintain its efficacy.

Application

• Industrial Water Treatment: Primary application as a highly effective scale inhibitor and dispersant for calcium carbonate, calcium sulfate, and barium sulfate in cooling water, boiler water, and reverse osmosis (RO) systems.
• Detergent & Cleaning Formulations: Acts as a builder and anti-redeposition agent in industrial and institutional cleaning products, enhancing performance in hard water.
• Pulp & Paper Processing: Used as a dispersant and deposit control agent to improve process efficiency and paper quality.
• Textile & Dyeing Auxiliary: Serves as a dispersing agent for dyes and pigments, ensuring uniform color and preventing agglomeration.
• Oilfield Chemicals: Applied in scale squeeze treatments and as a component in drilling muds to control mineral scaling.
• Construction Chemicals: Incorporated into cement admixtures and gypsum slurries to improve fluidity and workability.

Quality Control

Our production of this copolymer adheres to strict quality management protocols to ensure batch-to-batch consistency and performance reliability. Each lot is tested against key parameters including active polymer content, pH, viscosity, and residual monomer levels. A comprehensive Certificate of Analysis (COA) detailing these specifications is provided with every shipment. While produced under cGMP-like conditions for industrial use, specific grades can be tailored to meet customer-defined specifications or relevant industry standards.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive) and must be stored in a cool, dry place at a controlled room temperature (15-25°C). The original container should be kept tightly sealed when not in use to prevent moisture absorption, which can lead to caking and reduced performance. Store away from incompatible materials such as strong oxidizing agents.
