Overview
VAE Emulsion is an abbreviation for vinyl acetate–ethylene copolymer emulsion, which is a macromolecular emulsion, copolymerized by the high pressure emulsion polymerization method, after addition of emulsifier and initiator, with the vinyl acetate and vinyl monomer as the basic raw materials. VAE Emulsion is milk white or slight yellow in appearance.
Vinyl acetate–ethylene copolymer is an important product in the vinyl copolymer, generally in an emulsion state with its vinyl acetate content within a range of 70%-95%, and called as VAE Emulsion.
General properties
Product name: Vinyl Acetate Ethylene Copolymer Emulsion
Other name: Vinyl acetate-ethylene copolymer emulsion, VAE emulsion,VAE dispersion, Ethylene-vinyl acetate copolymer emulsion, EVA emulsion, Ethylene-vinyl acetate copolymer dispersion, EVA dispersion.
VAE Emulsion is the product based on the polar monomer vinyl acetate and the hydrophobic monomer ethylene. VAE Emulsion is produced by emulsion polymerization in an aqueous environment, without the addition of organic solvents.

Applications:
1. Versatility: VAE emulsions are highly versatile and can be tailored to meet specific requirements in different industries.
2. Adhesives: VAE emulsions are frequently used in the production of adhesives and sealants. They provide excellent adhesion to a wide range of substrates, making them suitable for applications such as woodworking, paper bonding, and construction adhesives.
3. Paints and Coatings: VAE emulsions are employed as binders in water-based paints and coatings. They contribute to the film-forming properties of these products, enhancing their durability, adhesion, and flexibility. They are also known for their low VOC (volatile organic compound) content, making them environmentally friendly.
4. Textile Industry: In the textile industry, VAE emulsions are utilized for textile coatings to improve the fabric's water and stain resistance. They also enhance the durability of printed patterns.
5. Paper Industry: VAE emulsions are used in paper coatings to improve the printability, surface finish, and ink holdout properties of paper products.
6. Construction: VAE emulsions find applications in construction materials, including cement and mortar modifiers, where they improve workability, adhesion, and durability.
7. Non-Woven Fabrics: VAE emulsions are used in the production of non-woven fabrics, providing strength and flexibility to the materials.
8. Emulsion Polymerization: They serve as a key component in the emulsion polymerization process to produce other types of polymers and latex products.
