Polyvinylpyrrolidone (PVP) is a water-soluble polymer certified to international standards.
It exhibits excellent water solubility, film-forming properties, and adhesion. It is widely used in tablet binders, coatings, solubilizers, and cosmetic stabilizers, improving process efficiency and product quality.
Its high purity and low impurity content ensure consistency and stability across a wide range of applications, helping customers optimize production costs and meet stringent regulations and market demands.
Product introduction
We are committed to providing customers with high-quality polyvinylpyrrolidone K30 (PVP K30). PVP K30 is a water-soluble linear polymer known for its excellent solubility, film-forming properties, adhesion, and complexing capabilities. Its average molecular weight is approximately 40,000-50,000 Da (K value 27.0-32.4) and it appears as a white or off-white, free-flowing powder at room temperature and pressure. This product is manufactured in strict accordance with international pharmacopoeia (EP/USP) and food grade (FCC) standards and complies with relevant regulations (such as FDA 21 CFR), ensuring its safety and efficacy. It can be directly used in applications requiring the highest purity.

Product Selection Guide
When selecting PVP K30 (polyvinylpyrrolidone K30), buyers should consider the following aspects to ensure the product meets application requirements while maintaining cost-effectiveness.
Recommendations:
1. Depending on the application scenario, prioritize PVP K30 that meets the corresponding industry standards to ensure regulatory compliance and market access.
2. If special requirements exist for solubility, film-forming properties, or adhesion, consider selecting a different grade or using a different molecular weight PVP based on the formulation.
3. High-end customers (pharmaceuticals/European and American exports) must select products with a full set of certifications to avoid registration or sales challenges.
4. Select a supplier with large-scale production to ensure competitive pricing and reduce delivery risks.
