Povidone K90
PVP K90
High-molecular-weight Povidone (PVP K90) for applications requiring stronger wet binding, higher solution viscosity, film-forming performance and stabilization support. Suitable for pharmaceutical granulation, tablet binding, medical patches, membrane materials, adhesives and selected specialty industrial formulations.
CAS No.: 9003-39-8
Yuking Povidone K90 is a high-molecular-weight polyvinylpyrrolidone (PVP) designed for applications requiring stronger wet binding, higher solution viscosity, film-forming performance, stabilization support or pore-forming functionality.
Also known as PVP K90, Povidone K90 is a water-soluble polymer that can be evaluated for pharmaceutical formulations, medical-device materials, membrane systems, adhesives, coatings and selected specialty industrial applications.
Compared with lower-molecular-weight PVP grades, Povidone K90 is generally selected when a formulation requires a higher-viscosity polymer profile, stronger binding capacity or enhanced adhesive and thickening performance.
Product Name: Povidone K90 / PVP K90 / Polyvinylpyrrolidone
Appearance: White to off-white powder
Standard Packaging: 25 kg cardboard drum
Storage: Keep sealed, shaded and protected from moisture.

Please request the latest Technical Data Sheet and Certificate of Analysis before supplier qualification. Product specifications, analytical methods and compliance status should be confirmed for the exact order grade and intended application.
Why Choose Povidone K90?
Povidone K90 is the highest-molecular-weight grade in the Yuking Povidone K Series. Its long polymer chains can provide stronger wet binding, higher viscosity and more pronounced film-forming performance than lower-K-value PVP grades.
Povidone K90 may be considered when your project requires:
Stronger binder performance for wet granulation or tablet production;
Higher solution viscosity in pharmaceutical or industrial systems;
A water-soluble polymer for film-forming applications;
Thickening or stabilization support;
Adhesive support for selected medical-patch or specialty adhesive systems;
A pore-forming agent for membrane materials;
A high-molecular-weight PVP for formulation development and process trials.
Final suitability should be confirmed through laboratory testing, pilot trials and process validation.
