Description

Maleic Anhydride-Methyl Acrylate Copolymer is a synthetic polymer derived from the copolymerization of maleic anhydride and methyl acrylate monomers. This versatile material is valued for its excellent dispersing, chelating, and scale inhibition properties in aqueous systems. It is primarily utilized in industrial water treatment, detergent formulations, and as a processing aid in various manufacturing sectors where control over mineral deposits and particulate matter is critical.

Application

• Industrial 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 builder and dispersant, enhancing cleaning efficiency by sequestering hardness ions and preventing soil redeposition.
• Pulp & Paper Processing: Used as a dispersant for pigments and fillers, and to control pitch and stickies.
• Textile Industry: Serves as a dispersing agent in dyeing processes and as an anti-redeposition agent in textile auxiliaries.
• Oilfield Chemicals: Employed in drilling fluids and production chemicals for scale inhibition and dispersion.
• Construction Chemicals: Incorporated as a superplasticizer and dispersant in cement admixtures and gypsum formulations.

Quality Control

Our Maleic Anhydride-Methyl Acrylate Copolymer is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent performance, including assessment of molecular weight distribution, solid content, pH, and residual monomer levels. A Certificate of Analysis (COA) documenting these parameters is provided with every shipment to guarantee compliance with your specifications and industry standards.

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). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after initial use to prevent moisture absorption and caking.
