VAE Full Form:


Vinyl Acetate Ethylene


What is VAE?


Copolymerization of vinyl acetate and ethylene results in the formation of vinyl acetate ethylene (VAE) copolymers. Water-based emulsions, or VAEs, are also available in powder form (construction adhesives). In low temperature and damp situations, VAEs provide exceptional moisture resistance, flexibility, better tack, and stickiness. On non-porous surfaces like vinyl, aluminum, etc., they stick well. VAE copolymers are used in laminating and packaging adhesives.


Rarely is vinyl acetate used in its pure state; it is an odorless liquid. Instead, it serves as a building block for other significant industrial chemicals. A total of 1.54 million metric tons of vinyl acetate were produced in the United States in 2019.


How is VAE made?


In processes involving bulk, solution, suspension, or emulsion, vinyl acetate monomer can be polymerized. The vinyl acetate monomer in the latter procedure may be 1200px-PVA. SVG was dissolved in water and began to polymerize, forming a milky white emulsion. The vinyl acetate monomers can be joined together to form lengthy branched chains of polymers when they are subjected to free-radical initiators.


Uses of VAE


It is clear now that VAE has various uses and this polymer is versatile in nature for sure. There are various things manufactured or produced with the help of VAE. Some of them are mentioned below-


Glues for Packaging
Sealing Layer for Bags (to pack the frozen food)
Benefits of VAE
VAE is Crack Resistance
Highly Transparent
Flexible and Endurance both at Low and Moderate Rate
Very Strong in Nature
Excellent Heat Seal Strength
