Description

Poly(Methyl Vinyl Ether-Alt-Maleic Anhydride) is a high-performance, alternating copolymer known for its excellent film-forming and adhesive properties. This versatile polymer is crucial for formulating products that require controlled solubility, pH responsiveness, and robust binding characteristics. It is essential for manufacturers in the pharmaceutical, personal care, and specialty coatings industries seeking reliable and consistent raw materials for advanced applications.

Application

• Pharmaceutical Excipient: Used as a binder, film-coating agent, and stabilizer in tablet formulations and controlled-release drug delivery systems.
• Personal Care & Cosmetics: Serves as a film-former and styling agent in hair sprays, mousses, and gels, and as a thickener/stabilizer in creams and lotions.
• Adhesives & Sealants: Acts as a key component in pressure-sensitive adhesives (PSAs) and industrial sealants due to its strong adhesion and cohesive strength.
• Specialty Coatings: Employed in the formulation of temporary protective coatings, textile finishes, and printing inks.
• Chelating Agent: Utilized in water treatment and detergent formulations for its ability to bind metal ions.
• Rheology Modifier: Functions as a thickener and suspending agent in aqueous systems for various industrial applications.
