VAE (vinyl acetate ethylene) polymers are a type of copolymer that is made by polymerizing vinyl acetate and ethylene. They are commonly used in adhesives, coatings, and other applications where they are known for their good film formation and ability to form strong bonds.

EVA (ethylene-vinyl acetate) hot melt is a type of hot melt adhesive made from EVA copolymer. It is a type of thermoplastic adhesive that becomes liquid when heated and solidifies when cooled. EVA hot melt is known for its good adhesion, flexibility, and low temperature properties. It is commonly used in a variety of applications including packaging, bookbinding, and lamination.

Overall, VAE polymers and EVA hot melt are similar in that they are both made from EVA copolymers, but they have different properties and are used for different purposes. VAE polymers are more commonly used in coatings and adhesives, while EVA hot melt is specifically used as a thermoplastic adhesive.
