Description

Poly(Maleicanhydride-Acrylicacidcopolymer) is a synthetic, water-soluble polymer known for its excellent scale inhibition and dispersant properties. This copolymer is highly valued for its ability to control mineral deposits and stabilize particulate matter in aqueous systems, which is critical for maintaining operational efficiency and preventing equipment fouling. It is an essential chemical for water treatment, detergent formulation, and industrial cleaning applications across multiple sectors.

Application

• Industrial Water Treatment: Acts as a highly effective scale inhibitor and dispersant for calcium carbonate, calcium sulfate, and barium sulfate in cooling water, boiler water, and reverse osmosis systems.
• Detergent & Cleaning Formulations: Used as a builder and anti-redeposition agent in laundry and dishwashing detergents to enhance cleaning power and prevent soil from re-adhering to fabrics or surfaces.
• Pulp & Paper Industry: Serves as a dispersant and chelating agent in pulp bleaching and papermaking processes to improve brightness and process efficiency.
• Textile Processing: Functions as a dye dispersant and anti-precipitant to ensure uniform dyeing and prevent scale formation in dye baths.
• Oilfield Chemicals: Employed in drilling fluids and production chemicals as a scale inhibitor to prevent mineral scale deposition in wells and pipelines.
• Industrial Cleaners: A key component in acid-based and alkaline cleaners for industrial equipment, providing superior sequestration of metal ions and dispersion of soils.

Quality Control

Our Poly(Maleicanhydride-Acrylicacidcopolymer) is manufactured under a strict quality management system. Each batch undergoes rigorous testing for critical parameters including assay, residual monomer content, molecular weight distribution, and pH to ensure consistent performance and compliance with industry standards. Certificates of Analysis (COA) documenting these specifications are available upon request.

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 opening to prevent caking and degradation due to moisture absorption.
