NINGBO INNO PHARMCHEM CO.,LTD. offers a comprehensive range of Polyvinylpyrrolidone (PVP) products, differentiated by their K-values, which correspond to varying molecular weights and viscosities. Understanding the nuances between grades like PVP K30 and PVP K90 is essential for optimizing product performance in pharmaceutical, cosmetic, and industrial applications. The K-value is a measure of the relative viscosity of a PVP aqueous solution, directly correlating with its average molecular weight.

Lower K-value grades, such as PVP K30, possess lower molecular weights and viscosities. They are typically favored for applications requiring less film stiffness or lower viscosity, such as in pump sprays or formulations where a lighter hold is desired. PVP K30 is an excellent binder and dispersant, finding common use in pharmaceutical tablets and cosmetic formulations where good binding without excessive stiffness is needed. Its versatility makes it a popular choice for a wide array of products.

Conversely, higher K-value grades like PVP K90 have significantly higher molecular weights and viscosities. This translates to stronger binding, more robust film formation, and increased viscosity in solutions. PVP K90 is particularly effective as a binder in tablet manufacturing, providing superior tablet strength. In hair styling, it offers a strong, long-lasting hold. The choice between grades often depends on the desired end-product characteristics. For instance, applications demanding high viscosity or strong film adhesion would benefit from PVP K90. NINGBO INNO PHARMCHEM CO.,LTD. provides expert guidance to help clients select the optimal PVP K-series grade, such as the highly effective PVP K90 for hair styling, to meet their specific formulation requirements. Proper selection ensures maximum efficacy and desired performance attributes.
