Product Name:PVPP
Chemical Description:Croslinked PVP,Crospovidone,Insoluble PVP,Pollyvinylpolypyrrolidone
INCI/CTFA:Insoluble PVP
CAS NO.:9003-39-8,25249-54-1
Formula Structure:
Packaging : 20 kg/fibre drum
Product Properties: PVPP is hygroscopic,insoluble in water and all other common solvents,but it swells rapidly in aqueous solutbition without any gel froms.
Thanks to its insoluble properties in water and other common solvents,PVPP is widely acted as stabilizers & clarifier for Beer/Wine and other beverages products,it can romove polyphenols and tannins substances during the Beer/Wine/Beverage processing.

Application:
Beverage industry:
PVP-P can be used in
-Improving the quality and extends the shelf-life of beer by absorbing the polyphenyls and tannoids.
- Prevention of 'pinking' and 'browning' reactions in white and sparkling wines
- Enhanced aroma and flavor in red wines
PVP-P is a cost-effective and safe treatment in beer industry that
- Completely insoluble in beer
- Applicable to all types of beer
- Higher efficacy - lower dosage
- Easy to use and excellent handling characteristics
- Insoluble process aids, with wide regulatory approval
- No negative impact on foam, flavor or other quality parameters
- Improved dispersion and sedimentation characteristics
- Longer filter run lengths compared to silica alone
- Uses existing plant equipment
