1. Adhesives and Coatings
This is its most classic and largest application. In its water-based emulsion form (white glue), it is widely used for bonding porous materials such as wood, paper, fabric, leather, and ceramics. It is also used in bookbinding, cigarette bonding, label adhesion, building decoration, and the preparation of latex paints.

2. Food and Daily Necessities
It is used as a base material for chewing gum, giving it its chewiness. It can also be used as a coating agent for fruits, providing a preservation effect.

3. Textiles and Nonwovens
It is used as a fabric finishing agent, in the manufacture of plush toys, and as a binder in the production of nonwoven fabrics.

4. Polymer Synthesis Raw Materials
Polyvinyl alcohol (PVA) can be prepared through hydrolysis reactions; it can also be used as a monomer in the production of copolymers such as vinyl acetate-ethylene (EVA) and vinyl acetate-vinyl chloride.

5. Biomedical and Pharmaceutical Applications
Due to its biocompatibility, biodegradability, and low toxicity, it is used in drug controlled-release formulations (such as floating tablets), wound dressings, artificial organs, and cardiovascular devices.

6. Special Functional Materials
It is used to prepare fibers or films for gas and humidity sensors. Due to its photosensitive properties, it can also be used as a photosensitive resin.
