Hangzhou Rainbow Import & Export Co., Ltd. is one of the leading manufacturers and suppliers of pvpp in China. With abundant experience, we warmly welcome you to buy customized pvpp from our factory. If you have any enquiry about free sample, please feel free to email us.
PVPP is a water-insoluble white or off-white powder with excellent adsorption properties and chemical stability. It is widely used in the pharmaceutical, food, and beverage industries, primarily as a clarifier, decolorizer, and adsorbent. Its porous structure adsorbs polyphenols, impurities, and other harmful components, thereby improving product purity and stability. This product is non-toxic, odorless, easily filterable, and reusable, making it a highly effective and safe functional polymer material.

PVPP Product Features
Appearance and Odor: White or milky white powder, odorless or with only a slight characteristic odor, essentially tasteless, with a clean and pure appearance.
Solubility: Insoluble in water, acids, alkalis, and most organic solvents. It exhibits excellent chemical stability and maintains stable performance in a variety of media.
Hygroscopicity and Swelling Properties: It exhibits significant hygroscopic and water absorption properties. Upon absorbing water, it rapidly swells without forming a gel, generating swelling pressure that causes rapid tablet disintegration.
Complexing Ability: Similar to soluble povidone, it can form complexes with compounds containing hydroxyl, carbonyl, and amino groups, thereby improving its solubility, odor, and toxicity.

High Quality PVPP Product Applications
Pharmaceutical Disintegrant
High-quality PVPP rapidly absorbs water and swells in tablets, generating swelling pressure that causes rapid tablet disintegration, improving drug dissolution rate and bioavailability.
Suspending and Dispersing Agent
Serves as a highly effective dispersant in liquid formulations, helping to maintain uniform distribution of drug particles, prevent precipitation, and enhance formulation stability.
Clarifying and Decolorizing Agent
Widely used in beverages such as beer, wine, and juice to clarify and decolorize, absorbing polyphenols and impurities, and improving taste and appearance.
Drug and Plant Extract Stabilizer
Forms complexes with drugs or plant ingredients, reducing oxidation and degradation, and extending product shelf life.
