PVA 0588 Application
PVA 0588 is a low viscosity, partially hydrolyzed polyvinyl alcohol grade with excellent water solubility, outstanding film-forming capacity and good surface activity. It is widely applied in multiple industrial fields as follows:
Used For Medicine Film & Outer pharmaceutical base material
It boasts good biocompatibility and low irritation, making it suitable for manufacturing soluble medicinal films and outer substrate materials for pharmaceutical preparations, thereby enabling controlled dissolution and safe contact with drug ingredients.
Used For Water-soluble Film
Thanks to stable dissolution performance and excellent leveling property, PVA 0588 is an ideal raw material for producing various environmentally friendly water-soluble films. The finished film features high transparency, a flat surface and moderate tensile property under standard processing conditions.
Used For High Count Flat Printing Photosensitive Film
Its stable viscosity, fine film formation and uniform spreadability make PVA 0588 a key additive for high-count flat-printing photosensitive film. It helps form an even photosensitive coating layer, improves resolution, enhances plate uniformity and optimizes printing definition.
Used For Paper making
Used as a surface sizing agent and coating binder in the papermaking industry. It can increase paper surface strength, reduce linting, improve smoothness and ink receptivity, effectively enhancing paper printability and surface finish
Used For Emulsions
Serves as a protective colloid, stabilizer and film-forming auxiliary for various emulsions. PVA 0588 improves emulsion system stability, prevents particle agglomeration, strengthens film toughness after drying and promotes uniform dispersion of emulsion components.
