Description

2-Butenedioic Acid (E)-, Polymer With Ethene is a high-performance copolymer of maleic acid and ethylene, known for its excellent chelating and dispersing properties. This versatile polymer is crucial for controlling scale and inhibiting corrosion in industrial water systems, offering superior performance over traditional phosphonates. It is an essential raw material for formulators in the water treatment, detergent, and textile processing industries seeking effective and environmentally compliant solutions.

Application

• Industrial Water Treatment: Primary application as a highly effective scale inhibitor and dispersant for calcium carbonate and phosphate scales in cooling water, boiler water, and reverse osmosis systems.
• Detergent & Cleaning Formulations: Acts as a builder and co-builder, enhancing cleaning power by sequestering hardness ions (Ca²⁺, Mg²⁺) and preventing inorganic salt deposition on fabrics and surfaces.
• Pulp & Paper Processing: Used as a dispersant and chelant in pulp bleaching and papermaking to improve process efficiency and product quality.
• Textile Auxiliary: Serves as a dispersing agent in dyeing processes and as a scale preventer in textile finishing baths.
• Oilfield Chemicals: Employed in scale control formulations for downhole and topside applications to maintain well productivity and flow assurance.
• Personal Care Products: Incorporated into formulations such as shampoos and soaps as a chelating agent to improve stability and performance in hard water.

Quality Control

Our 2-Butenedioic Acid (E)-, Polymer With Ethene is manufactured under a stringent quality management system. Each batch is tested to ensure consistent performance in key parameters such as molecular weight distribution, solids content, and active acid content. Certificates of Analysis (COA) documenting these specifications are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive). Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep the container tightly sealed when not in use to prevent moisture absorption and caking.
