NINGBO INNO PHARMCHEM CO.,LTD. offers a comprehensive range of Polyvinylpyrrolidone (PVP) products, distinguished by their K-values, which denote varying molecular weights and viscosities. This K-series of polymers, including popular grades like PVP K17, K30, and K90, presents a spectrum of functionalities tailored for diverse industrial applications, from pharmaceuticals to personal care and beyond.

The K-value of PVP is a critical indicator of its molecular weight and, consequently, its performance characteristics. Lower K-values, such as K17, are typically associated with lower viscosities and are often used as solubilizing agents, crystallization inhibitors, and suspension stabilizers, particularly in ophthalmic and injectable formulations where precise viscosity control is paramount. Their excellent water solubility and low toxicity profile make them suitable for sensitive applications.

Medium molecular weight grades, like PVP K30, bridge the gap with a balance of binding, film-forming, and solubilizing properties. These are widely utilized as binders in tablets and granules, dispersants for pigments, and film-forming agents in cosmetics. The versatility of PVP K30 allows it to be incorporated into a broad range of products, enhancing texture and stability. Its application in hair styling products, for instance, leverages its ability to provide hold and control.

At the higher end of the spectrum, PVP K90, with its significantly higher molecular weight and viscosity, serves as a highly effective binder and thickener. It is preferred in applications requiring substantial viscosity modification and strong film formation, such as in certain cosmetic formulations or as a stabilizer in suspensions. The choice between these grades depends heavily on the specific performance requirements of the end product. Understanding these nuances is key to selecting the optimal PVP grade for any given application. For businesses looking to source these versatile polymers, focusing on manufacturers providing detailed technical data and consistent quality is essential.
