Polyvinylpyrrolidone (PVP) K90: A Polymer with Unmatched Versatility

Introduction

Polyvinylpyrrolidone (PVP), particularly its high molecular weight variant known as PVP K90, is a polymer that has gained acclaim for its exceptional versatility and effectiveness across a vast array of applications. Renowned as an indispensable binder and stabilizer, PVP K90 plays a pivotal role in industries ranging from pharmaceuticals to cosmetics, where it significantly enhances product quality and performance. In this showcase article, we will explore the core attributes and wide-ranging uses of PVP K90 while highlighting its popularity and importance in modern manufacturing processes.

What is PVP K90?

PVP K90, or Polyvinylpyrrolidone K90, is a synthetic polymer distinguished by its high molecular weight and excellent solubility. One of its standout features is its ability to form strong, clear, and flexible films, making it essential for numerous industrial applications. The "K90" designation refers to the viscosity grade of the polymer, indicating a K-value typically ranging from 81 to 97. This higher K-value translates to superior binding properties compared to lower molecular weight forms like PVP K30, allowing for robust performance in demanding applications.

PVP K90 is not only soluble in water but also in various organic solvents, which broadens its utility in diverse formulations. Notably, it is characterized by its non-irritating and non-toxic nature, making it safe for inclusion in products intended for human use.
