[applications]
Because of high molecular weight and crosslinking structure, PVPP can not dissolve in water but can quickly adhibit water and make its network structure expand and breakdown. So PVPP is widely used as disintegrating agent and bulking agent of troche, pelletized granule and capsule in pharmaceutical area. And the molecule has amido bond and adsorb hydroxyl of polyphenol molecule to form hydrogen bond, therefore it can uses as stabilizer of beer, ratafee and potable spirit, prolong the quality guarantee duration to 300 days, and also can improve the transparence, color and taste.
