Application
PVPP, as an important polymer fine chemical product, has many excellent and unique properties, and has been widely used in cosmetics, food, medicine and other fields. Due to the high molecular weight and cross-linking structure of cross-linked polyvinylketone, it is insoluble in water but can quickly cause its network structure to expand and undergo disintegration when encountering water. PVPP is widely used as a disintegration agent for tablets in medicine, as well as as a suspension stabilizer, a complexing agent for pharmaceutical components, and a complexing agent for tannins and polyphenols in plant-based drugs.
