Description

2,5-Furandione, Polymer With Ethenylbenzene, Ammonium Salt is a synthetic, water-soluble polymer derived from maleic anhydride and styrene, subsequently neutralized to its ammonium salt form. This specialized copolymer is valued for its excellent dispersing, scale-inhibiting, and chelating properties in aqueous systems. It is a critical performance additive for industrial water treatment, detergent formulations, and mineral processing applications where control of inorganic deposits and particulate dispersion is required.

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 anti-redeposition agent, enhancing cleaning power and preventing soil from re-adhering to fabrics or surfaces.
• Pulp & Paper Industry: Used as a dispersant and deposit control agent to improve process efficiency and paper quality.
• Mineral Processing: Serves as a dispersant in slurry transport and mineral beneficiation processes to prevent agglomeration.
• Textile Auxiliary: Employed in dyeing and finishing processes to improve color uniformity and prevent scale buildup on equipment.
• Ceramic & Construction: Acts as a grinding aid and plasticizer in ceramic slips and cement admixtures to control rheology.

Quality Control

Our production of 2,5-Furandione, Polymer With Ethenylbenzene, Ammonium Salt adheres to stringent quality management protocols. Each batch is tested to ensure consistent performance characteristics such as molecular weight distribution, solids content, pH, and viscosity. Certificates of Analysis (COA) documenting these parameters are provided with every shipment to guarantee product integrity and traceability for our global B2B clients.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product performance.
