Description

Poly((Isobutylene-Alt-Maleic Acid) Ammonium Salt is a high-performance, water-soluble copolymer derived from isobutylene and maleic anhydride, subsequently neutralized with ammonia. This versatile polymer is valued for its exceptional dispersing, scale inhibiting, and chelating properties in aqueous systems. It is a critical additive for industrial water treatment, detergent formulations, and mineral processing, where it effectively controls hardness ions and prevents unwanted deposits.

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: Functions as a superior builder and anti-redeposition agent in laundry and dishwashing detergents, enhancing cleaning power and preventing soil from re-adhering to fabrics.
• Mineral Processing & Dispersion: Used as a dispersing agent for pigments, clays, and inorganic fillers in paper coatings, ceramics, and construction materials to improve stability and processing.
• Textile Industry: Serves as a dye dispersant and anti-precipitant to ensure uniform dyeing and prevent scale buildup on machinery.
• Oilfield Chemicals: Employed in scale control formulations for production wells and squeeze treatments to maintain wellbore permeability.
• Personal Care Products: Utilized in select formulations as a viscosity modifier and stabilizer due to its anionic polyelectrolyte nature.

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 material is hygroscopic (moisture-sensitive); keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which may affect product performance.
