Poly(N-vinylpyrrolidone), MW 40,000

Poly(N-vinylpyrrolidone) (PVP) is a water-soluble polymer synthesized through free-radical polymerization of N-vinylpyrrolidone. Known for its exceptional biocompatibility and hydrophilicity, PVP exhibits high solubility in both aqueous and organic solvents, along with excellent film-forming and adhesive properties.
Pharmaceuticals: Binder in tablets, stabilizer in suspensions, and component of wound dressings.
Medical Devices: Lubricious coatings for catheters, surgical tools, and contact lenses.
Personal Care: Hair styling gels, creams, and lotions as a film-former and stabilizer.
Adhesives: Improves adhesion in water-based and pressure-sensitive adhesives.
Filtration: Membrane manufacturing for water and gas filtration systems.
