Description

Isopropyl Ester Of Pvm/Ma Copolymer is a specialized synthetic polymer derived from the copolymerization of maleic anhydride and methyl vinyl ether, subsequently esterified with isopropanol. This compound is valued for its excellent film-forming, binding, and suspending properties, making it a critical functional additive in advanced formulations. It is primarily sought after by manufacturers in the personal care, pharmaceutical, and industrial coating sectors seeking to enhance product performance and stability.

Application

• Hair Styling Products: Serves as a primary film-forming agent and fixative in hair sprays, gels, and mousses, providing strong hold with good flexibility and humidity resistance.
• Skin Care & Color Cosmetics: Used as a binder and stabilizer in sunscreens, foundations, and mascaras, improving water resistance and ensuring uniform pigment dispersion.
• Pharmaceutical Coatings: Employed in the formulation of enteric and sustained-release tablet coatings, offering precise control over drug dissolution profiles.
• Industrial Adhesives & Sealants: Acts as a key component in pressure-sensitive adhesives and specialty sealants, contributing to tack, cohesion, and environmental stability.
• Printing Inks: Functions as a rheology modifier and dispersing agent, enhancing ink gloss, flow properties, and pigment suspension.

Quality Control

Our Isopropyl Ester Of Pvm/Ma Copolymer is manufactured under a strict quality management system. Each batch is tested against rigorous in-house specifications to ensure consistent performance, including parameters for viscosity, solids content, residual solvents, and acid value. Certificates of Analysis (COA) documenting these results are available upon request to support your quality assurance and regulatory compliance needs.

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); the container must be kept tightly sealed to prevent moisture absorption, which can affect product performance.
