1. Adhesives:

PVA is widely used as a binder in adhesives and glues. It provides good adhesion to a wide range of surfaces, including paper, wood, fabric, and ceramics. PVA-based adhesives are commonly used in woodworking, packaging, and crafts.

2. Packaging:

PVA is utilized in packaging applications due to its excellent film-forming properties and barrier properties. It is used to create thin films or coatings on products to improve their moisture resistance, prolong shelf life, and protect against external factors such as gases and odors.

2. Textiles:

PVA is employed in the textile industry as a sizing agent to improve the weaving and processing of yarns. It imparts strength, stiffness, and abrasion resistance to fabrics, enhancing their overall quality. PVA sizing is particularly useful for synthetic and blended fibers.

3. Paper Industry:

PVA is used in the paper manufacturing process to improve paper strength, surface smoothness, and printability. It is applied as a coating or additive to enhance ink absorption, reduce ink bleeding, and provide a glossy finish to paper products.

4. Construction Materials:

PVA is utilized in construction applications, such as cement and mortar additives. It improves the workability, bonding strength, and flexibility of these materials. PVA-based formulations are used in tile adhesives, plasters, and grouts.

5. Pharmaceutical and Medical Applications:

PVA hydrogels, formed by crosslinking PVA chains, have applications in pharmaceuticals and medical fields. They can be used as drug delivery systems, wound dressings, contact lens materials, and artificial tissue scaffolds.
