Polyvinylpyrrolidone K90 (PVP K90) is a high molecular weight water-soluble polymer with exceptional viscosity performance and multi-industry adaptability. With a molecular weight exceeding 1,000,000+, it delivers outstanding binding, film-forming, and dispersing capabilities for demanding industrial applications.

Designed for regulated industries and high-performance systems, PVP K90 is widely used in pharmaceuticals, cosmetics, medical membranes, and industrial formulations, where stability, compliance, and consistency are critical.
