Description

2-Butenedioic Acid (2Z)-, Sodium Salt, Polymer With 2-Propenoic Acid, Sodium Salt, Peroxydisulfuric Acid ([(Ho)S(O)2]2O2) Disodium Salt-Initiated is a high-performance, water-soluble copolymer designed for demanding industrial applications. This specialized polymer offers superior sequestering and dispersing properties, making it a critical additive in formulations requiring scale inhibition and particulate suspension. It is primarily utilized by manufacturers in the water treatment, detergent, and textile processing industries where consistent quality and reliable performance are paramount.

Application

• Water Treatment: Acts as a highly effective scale and corrosion inhibitor in cooling water, boiler water, and reverse osmosis systems.
• Detergent & Cleaning Formulations: Functions as a superior builder and dispersant to enhance cleaning power and prevent redeposition of soil in laundry and industrial cleaners.
• Textile Processing: Used as a dispersing and chelating agent in dyeing and printing processes to improve color uniformity and fastness.
• Pulp & Paper Manufacturing: Serves as a dispersant and chelant to control pitch and improve pulp brightness and paper quality.
• Industrial Cleaning: Key component in formulations for metal cleaning, circuit board etching, and equipment descaling due to its sequestering power.
• Oilfield Chemicals: Employed in drilling muds and production chemicals as a scale inhibitor and fluid loss control additive.

Quality Control

Our production of this copolymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Each lot undergoes comprehensive analysis, including assay, residual monomer content, and viscosity measurement. Certificates of Analysis (COA) documenting all critical parameters are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after each use to prevent moisture absorption, which can affect product performance.
