High-Purity Polyvinylpyrrolidone K90 9003-39-8 Features

High Viscosity Performance

Compared with lower molecular weight grades such as PVP K25 and PVP K30, PVP K90 provides stronger thickening and binding capabilities. Its high molecular weight structure allows it to improve formulation viscosity, enhance adhesion, and deliver better performance in applications requiring strong binding properties.

Excellent Film-Forming Ability

PVP K90 can create a transparent, flexible, and uniform film after drying. This film-forming property helps improve product appearance, surface protection, and long-lasting performance, making it suitable for cosmetic, pharmaceutical, and industrial formulations.

Outstanding Stability

PVP K90 offers good compatibility and stability under various formulation conditions. It maintains reliable performance in systems containing acids, alkalis, and different types of salts, helping manufacturers achieve consistent product quality.

Good Moisture Retention Performance

With excellent hygroscopic properties, PVP K90 helps maintain moisture balance within formulations. It can improve texture, prevent excessive drying, and contribute to better stability during storage and use.

High Safety and Compatibility

Pharmaceutical-grade PVP K90 meets strict quality requirements for use as a pharmaceutical excipient. Its excellent biocompatibility and compatibility with active ingredients make it widely used in tablet binding, drug delivery systems, and other medical formulations.

Comparison of Different PVP Grades

Product Grade	Molecular Weight Level	Main Characteristics	Common Applications
PVP K25	Low molecular weight	Fast dissolution, good fluidity, and easy processing performance	Pharmaceutical formulations, cosmetics, and personal care products
PVP K30	Medium molecular weight	Balanced viscosity, excellent solubility, and versatile performance	Tablet binders, skincare products, and general pharmaceutical applications
PVP K60	Higher molecular weight	Higher viscosity, improved thickening ability, and enhanced stabilization performance	Thickening systems, stabilizers, and specialty formulations
PVP K90	High molecular weight	High viscosity, strong binding capacity, excellent film-forming ability, and superior adhesion performance	Pharmaceutical excipients, industrial thickeners, film-forming agents, and high-performance formulations
