Description

Pvm/Ma CAS NO 1644545-52-7 is a high-purity copolymer of vinyl methyl ether and maleic anhydride, valued for its versatile film-forming and binding properties. This material is essential for formulators requiring consistent performance and reliable supply chain integrity. It is primarily utilized in the pharmaceutical, personal care, and specialty adhesive industries for its excellent biocompatibility and functional characteristics.

Application

• Pharmaceutical Coatings: As a primary or secondary film-forming agent for enteric and sustained-release tablet coatings.
• Hair Styling Products: Key polymer in mousses, gels, and sprays to provide strong hold with good washability.
• Oral Care Films: Used in dissolvable oral strips and breath freshener films for its solubility and binding strength.
• Transdermal Patches: Serves as a bioadhesive matrix component for controlled drug delivery systems.
• Specialty Adhesives: A functional additive in pressure-sensitive and water-based adhesives to enhance tack and cohesion.
• Industrial Binders: Employed in the production of ceramics, textiles, and non-woven fabrics.

Quality Control

Our Pvm/Ma CAS NO 1644545-52-7 is manufactured under a strict quality management system. Each batch is tested to ensure compliance with relevant pharmacopeial standards (such as USP-NF) and internal specifications for critical parameters like molecular weight distribution, residual solvents, and acid value. A comprehensive Certificate of Analysis (COA) is provided with every shipment to guarantee traceability and product consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and must be kept in its original packaging until use to prevent moisture uptake, which can affect performance.
