For procurement managers and research scientists in the chemical and pharmaceutical industries, identifying reliable sources for specialized materials is key to successful product development and manufacturing. Poly(methyl vinyl ether-alt-maleic anhydride) (PMVE-MA), identified by its CAS number 9011-16-9, is one such critical ingredient. NINGBO INNO PHARMCHEM CO.,LTD., a leading manufacturer and supplier in China, provides essential guidance for businesses looking to buy this versatile copolymer.

Key Considerations for Purchasing PMVE-MA

When evaluating suppliers for PMVE-MA, several factors are paramount to ensure you are receiving a product that meets your exacting standards:

  • Purity and Assay: The active ingredient content, typically exceeding 98.0%, is a fundamental specification. Higher purity translates to more predictable performance and fewer complications in downstream processing, especially critical for pharmaceutical applications.
  • Molecular Weight and Viscosity: The intrinsic viscosity range (e.g., 0.1-4.0) is a direct indicator of molecular weight and polymer chain length. Different applications, such as denture adhesives versus industrial coatings, may require specific viscosity profiles. A knowledgeable supplier can help match you with the right grade.
  • Appearance and Physical Form: While generally supplied as a white or off-white powder, consistency in appearance can signal consistent manufacturing quality.
  • Residual Impurities: Trace amounts of residual maleic anhydride or other by-products should be minimized. Low loss on drying (≤2.0%) is also a desirable attribute for product stability.

Applications and Market Demand

The demand for PMVE-MA stems from its diverse applications:

  • Denture Adhesives: This is a primary market, where the copolymer’s excellent bioadhesive and film-forming properties provide superior hold and comfort.
  • Pharmaceutical Excipients: Its use in controlled-release drug delivery systems and enteric coatings highlights its importance in the pharmaceutical sector.
  • Coatings and Sealants: Industrial applications leverage its adhesive and binding capabilities for enhanced product performance.
