PVA Application
1.Textile Warp sizing agent
Protective coating for natural fiber and synthetic fiber before weaving in textile industry. It help increases the tensile strength of the yarn, reducing the breakage rate.
2.Textile/Fabric finishing chemicals
Textile finishing chemicals used in processing, giving textile more stiff, anti-wrinkle, anti-shrinking, or other specific properties.
3. Glue
PVA Glue, as a key component in water-based adhesives, such as white glue and wood glue. It acts as a protective colloid, providing excellent film-forming properties, strong adhesion to porous surfaces like paper, wood, and fabric, and good resistance to oils and solvents.
4. Paper industry
PVA applied as a surface sizing agent to improve the paper strength, enhancinig oil and crease resistance. Also provides a smooth surface that absorbs ink evenly. More, PVA is used as a binder in pigment coatings, including binding pigments, improving gloss and brightness, and increasing stiffness.
5. Plywood woodworking industry
Polyvinyl Alcohol can be a de-characterizing agent of thermosetting resin mainly used as a binding agent such as carbamide, formaldehyde resin and melamine, for plywood, artificial board and timber processing.
6. PVAc, PVC, PS
Stabilizer for emulsion, protective colloids.PVA is used as a protective colloid for the polymerisation of PVAC. Prevents polymer particles from coalescing (sticking together) during polymerization. And used in suspension polymerization (e.g., for PVC) to disperse monomer droplets in water.
7. Construction industry
Cement additives, and molding adhesives. It enhances cement adhesion, fluidity and slow down the cement surface drying time, improve their workability, preventing cracking.
8. Raw material for PVA sponge and grinding discs sanding paper
Raw material for PVA sponge and grinding discs sanding paper. PVA serves as the structural matrix and the absorbent material. It provides sponge's shape and resilience, while its hydrophilic nature enables rapid water absorption and retention.
9. Packaging material
Water soluble films, laundry pods film. PVA has cold water solubility and high barrier properties. It is widely used in laundry pods/dishwasher detergent packets, laundry detergent, agricultural chemical packaging embroidery backing films, unit-dose packaging.
10. Printing industry
Screen printing photosensitive films (Photographic plate photosensitive film), and zinc plate priniting photosensitive films.
