Product Description

Product Description

Crosslinked Povidone/PVPP/Cas#25249-54-1

Cas No.:25249-54-1

Molecular Formula:C6H9NO

Alias:PVP cross-linked; Povidone cross-linked; Polyvinylpyrrolidone cross-linked; 1-ethenylpyrrolidin-2-one; PVPP; Crosslinked Povidone;Polyvinylpolypyrrolidone cross-linked

Description: PVP-P behaves as a white or creamy white powder with faint characteristic odor, which is easily hydrophilic and capable of complex with such substance as phenol, etc. It is completely insoluble with relatively high crosslink density and does not form gels that can impede disintegration, dissolution and release. It was accepted into Ph Eur 5.0 and USP/NF28th.

Specification :

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

Package:20kg/drum

Shelf life: 24months
Storage: Sealed, Avoid light, stored in dry and cool place; no mixing with toxic and hazardous articles. It is non-dangerous article, and can be transported as common chemicals; handle with care; protect against sunlight and rain.
Quality Index:Ph Eur 5.0 and USP/NF28th.
