Product application
1. Pharmaceutical Industry (Core Excipient)
As a global top-tier excipient, PVP K30 serves multiple roles:
Tablet Binder: Enhances mechanical strength and stability of solid dosage forms.
Solubilizer: Improves the bioavailability of poorly soluble drugs in oral liquids and injectables.
Stabilizer: Protects heat-sensitive active ingredients from degradation.
Sustained Release: Controls the drug release rate to minimize side effects and maximize efficacy.
2. Water Treatment & Membranes
Used as a high-performance pore-forming agent (porogen) in ultrafiltration and microfiltration membranes.
Pore Control: The molecular weight (~40,000 Da) ensures precise pore size distribution.
Hydrophilicity: Residual PVP enhances membrane surface hydrophilicity, significantly improving anti-fouling performance.
3. Cosmetics & Personal Care
Film-Former: Ideal for hair sprays and gels for long-lasting hold.
Thickener & Stabilizer: Manages rheological properties in creams and lotions.
Dispersant: Ensures uniform color distribution in decorative cosmetics.
4. Industrial & High-Tech Applications
Lithium Battery Slurry: Acts as a dispersing medium for conductive agents.
3D Printing: Improves slurry flow and structural integrity.
