PVP VA64 is a white to milky white amorphous powder that is odorless, hygroscopic, and readily soluble in water and various organic solvents. It combines the excellent water solubility and film-forming properties of PVP with the low water absorption and high plasticity of PVAC. It is commonly used as a tablet binder, coating film-forming agent, and spray film-forming aid in pharmaceutical preparations, exhibiting excellent flexibility and stability.

PVP VA64 Main Application Areas
Dual Functional Advantages
Combines the key properties of PVP and PVAC, maintaining PVP's excellent water solubility, adhesion, and film-forming ability, while providing lower hygroscopicity, broader solubility, higher plasticity, and stronger surface activity.
Outstanding Binder Performance
Serves as a superior binder for tablet and granule formulations. Tablets made with PVP VA64 exhibit high hardness, low friability, and reduced stickiness during humid conditions, making it ideal for high-dose, poorly soluble, or moisture-sensitive drugs.
Excellent Film-Forming Properties
Acts as an efficient film-forming agent for tablet coatings, pellets, granules, and topical sprays. The resulting films have good flexibility, low moisture absorption, high plasticity, and smooth appearance.
Versatile Processing Compatibility
Suitable for wet granulation, dry granulation, and direct compression. When used for film coating, it is often combined with cellulose derivatives, shellac, or polyethylene glycol to improve film strength, flexibility, and solubility.
