Description

Poly(Isobutylene-Co-Maleic Acid) Sodium Salt is a versatile, water-soluble copolymer derived from isobutylene and maleic anhydride. This compound is valued for its excellent dispersing, scale-inhibiting, and viscosity-modifying properties in aqueous systems. It is a critical additive for formulators in the water treatment, detergent, and personal care industries seeking to enhance product performance and stability.

Application

• Water Treatment: Acts as a highly effective dispersant and antiscalant in cooling water, boiler water, and reverse osmosis systems.
• Detergents & Cleaners: Functions as a builder and anti-redeposition agent, improving cleaning efficiency and preventing soil from re-adhering to fabrics.
• Personal Care & Cosmetics: Used as a thickener, stabilizer, and film-forming agent in shampoos, creams, and lotions.
• Textile & Leather Processing: Serves as a dispersing agent for dyes and pigments, and as a tanning auxiliary.
• Paper & Pulp Industry: Employed as a retention aid, dispersant, and for pitch control.
• Coatings & Paints: Enhances pigment dispersion and stabilizes latex formulations.
• Agriculture: Used in pesticide and fertilizer formulations as a dispersant and adjuvant.
• Oilfield Chemicals: Functions as a scale inhibitor and fluid loss additive in drilling muds.

Quality Control

Our Poly(Isobutylene-Co-Maleic Acid) Sodium Salt is manufactured under a strict quality management system. Each batch undergoes rigorous testing to ensure consistent performance, including analysis of active content, pH, viscosity, and residual monomers. Certificates of Analysis (COA) are 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); keep the container tightly sealed to prevent absorption of atmospheric moisture which may affect performance.
