Polyvinyl Alcohol Powder (PVA) Functions

Solution Stability

Polyvinyl Alcohol Powder (PVA) delivers excellent solution stability, preventing sedimentation or separation even during long storage, ensuring consistent performance in formulations.

Solubility

PVA dissolves well in water at appropriate temperatures, forming uniform solutions without lumps, enabling easy integration into various applications.

Film Formation

It forms flexible, transparent, and strong films with good barrier properties against gases and oils, suitable for coatings, adhesives, and packaging-related uses.

Adhesion

It has good adhesion to cement and other gelling materials.
