poly(vinyl acetate) Application scenarios
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.

Poly(vinyl acetate) Usage
1. As a gum base, China’s regulations can be used for emulsified flavors and gums, the maximum use is 60g / kg.
2. Used to make toy velvet and non-woven fabric
3. Used as a raw material for polyvinyl alcohol, vinyl acetate-vinyl chloride copolymer, vinyl acetate-ethylene copolymer, also used in the preparation of coatings, adhesives, etc.
4. Mainly used as coatings, adhesives, paper, chewing gum bases and fabric finishing agents, as well as raw materials for polyvinyl alcohol and polyvinyl acetal
5. The basic gum base of gum sugar; the fruit coating agent prevents moisture from evaporating and plays a role in preserving freshness.
6. The thermoplastic resin is hydrolyzed into polyvinyl alcohol in an acid or alkaline solvent to prepare a main raw material of polyvinyl alcohol. When the molecule contains a photosensitizer, it is sensitive to light, and undergoes a decomposition reaction under the action of ultraviolet light or electron beam, and has a positive photosensitive resin property. Polyvinyl acetate is soluble in a variety of organic solvents and can be copolymerized with a variety of monomers with double bonds to introduce various functional groups with different properties. Often used as a binder.
7. Used as a raw material for polyvinyl alcohol, vinyl acetate-vinyl chloride copolymer, vinyl acetate-ethylene copolymer, paint, binder, bubble gum, etc.
