Product introduction
Polyvinylpyrrolidone (PVP), also known as Povidone is a high-performance water-soluble polymer widely used as a binder, dispersant, stabilizer, film former, and solubilizer across pharmaceuticals, cosmetics, food processing, and industrial manufacturing.
We offer a complete range of PVP K-values to match different industrial needs:
PVP K15 / K17 – Low viscosity, fast dissolution, ideal for coatings and cosmetics
PVP K25 / K30 – Balanced performance for pharmaceuticals, food, and industrial dispersion systems
PVP K60 – Medium-high viscosity, strong binding and stabilization performance
PVP K90 / K120 – High molecular weight grades for advanced membranes, adhesives, and high-strength formulations

Product Applications
1. Pharmaceutical & Life Sciences
PVP K30 (Binder & Solubilizer): Ideal for tablet binding and oral liquids. It increases the mechanical strength of tablets and improves the bioavailability of poorly soluble drugs.
PVP K90 (Medical Membranes): A critical raw material for Kidney Dialysis Membranes. It allows for molecular-level precision, clearing urea/creatinine (<500Da) while retaining essential serum proteins (>66kDa).
Safety Advantage: Excellent blood compatibility; reduces the risk of thrombosis by inhibiting platelet adhesion.
2. Lithium Battery & Industrial Tech
Conductive Agent Dispersion: PVP K30/K90 increases the dispersion efficiency of lithium battery slurries by 50%, ensuring a more stable electrochemical performance.
Water Treatment: Used as a pore-forming agent in PSF (Polysulfone) membranes. It regulates pore size (2-5nm) and enhances hydrophilicity to prevent membrane fouling.
3. Cosmetics & Personal Care
Film-Forming: PVP K90 extends makeup wear-time by 6+ hours.
Rheology Control: Acts as a thickener and stabilizer in hair gels and masks, providing a smooth spread without clumping or "stringing."
4. Adhesives & Specialty Chemicals
PVP K90 in Glue Sticks: Provides superior initial tack and long-term stability. It ensures smooth application without edge warping, maintaining performance from -20°C to 50°C.
