FAQ

1.What is the difference between cross-linked PVP and ordinary PVP?
Cross-linked PVP introduces cross-linking points in the molecular structure to form a three-dimensional network structure, which makes it insoluble in water or other solvents. Ordinary PVP is easily soluble in water and other solvents and is usually used in adhesives, thickeners and other applications.

2. What are the main uses of cross-linked PVP?
Drug release control: As a drug carrier, it helps control the drug release rate.
Food clarification: Used for clarification of beverages such as wine, beer, and juice to remove impurities and pigments.

3. Is cross-linked PVP harmful to the human body?
Cross-linked PVP is a food and drug additive that has undergone rigorous safety assessment. It is not absorbed by the human body and usually does not cause harm to the human body during use.

4. How to remove cross-linked PVP?
It is usually insoluble in water or conventional solvents during use, so its residues can be removed by physical filtration, precipitation or centrifugation.

5. Is cross-linked PVP suitable for all types of beverages and foods?
Suitable for aqueous beverages and liquid foods such as wine, beer, juice, etc.
