PVA

(Polyvinyl Alcohol)

Introduction

Polyvinyl alcohol (PVA), a white/yellowish granule or powder, is a stable, non-toxic, and water-soluble polymer. PVA possesses superb film-forming property, and the produced film has excellent adhesion, solvent-resistance, abrasion-resistance, tensile strength, and oxygen barrier. Since PVA possesses both hydrophilic and hydrophobic functional groups, it can act as a surfactant, and can be used as a protective colloid in polymer emulsification and suspension polymerization.

 

Application

1.Warp sizing agent:Protective coating for natural fiber and synthetic fiber.

2.Textile/Fabric finishing chemicals:Textile finishing chemicals used in processing, giving the textile more stiff, anti-wrinkle, anti-shrinking, or other specific properties.

3.Screen printing:Temporary adhesive for screen printing machine.

4.Paper industry:Paper adhesive, re-wetting adhesive, surface coating, pigment coating, and internal sizing.

5.Plywood, woodworking industry:Modifier for thermosetting resins.

6.Construction industry:Cement additives and molding adhesives.

7.Raw material for PVA sponge and grinding discs sanding paper.

8.PVAc, PVC, PS:Stabilizer for emulsion, protective colloids.

9.Packaging material:PVA films.

10.Printing industry:Screen printing photosensitive films (photographic plate photosensitive films and zinc plate printing photosensitive films).
