Description

2-Butenedioic Acid (2Z)-, Polymer With Ethenylbenzene is a synthetic copolymer derived from maleic acid and styrene. This polymer is valued for its ability to act as a versatile dispersant, scale inhibitor, and rheology modifier in aqueous systems. It is primarily needed by manufacturers in the water treatment, construction, detergent, and textile industries seeking to control deposition and improve process stability.

Application

• Water Treatment: Acts as a highly effective antiscalant and dispersant for calcium carbonate, sulfate, and phosphate scales in cooling water, boiler water, and reverse osmosis systems.
• Construction Chemicals: Used as a superplasticizer and water-reducing agent in concrete admixtures to improve workability and final strength.
• Detergent & Cleaning Formulations: Functions as a builder and anti-redeposition agent to enhance cleaning efficiency and prevent soil from re-adhering to fabrics.
• Textile Processing: Serves as a dispersing agent for dyes and pigments, ensuring uniform color application and preventing agglomeration.
• Paper & Pulp Industry: Utilized as a retention aid and dispersant to improve paper quality and production efficiency.
• Oilfield Chemicals: Applied in drilling muds and production chemicals to control scale and disperse solids.
• Paints & Coatings: Acts as a pigment dispersant and stabilizer to prevent settling and maintain viscosity.
• Industrial Cleaning: Formulated into acidic and alkaline cleaners for industrial equipment to inhibit scale formation.

Quality Control

Our Styrene Maleic Acid Copolymer is manufactured under a strict quality management system. Each batch undergoes rigorous testing to ensure consistent performance, including analysis of molecular weight distribution, acid value, and solid content. Certificates of Analysis (COA) documenting key specifications are available upon request to support your quality assurance protocols.

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 opening to prevent moisture absorption, which can affect product performance.
