No, Ethylene Vinyl Acetate (EVA) is not the same as Vinyl Acetate-Ethylene (VAE). While both EVA and VAE are copolymers of ethylene and vinyl acetate, they have different structures and properties.
EVA is a copolymer of ethylene and vinyl acetate, where the vinyl acetate content typically ranges from 5% to 50% by weight. It is a flexible, rubbery material commonly used in various applications such as footwear, packaging, and solar cell encapsulation due to its excellent flexibility, low-temperature toughness, and UV resistance.
VAE, on the other hand, refers to a different type of copolymer formed by the polymerization of vinyl acetate and ethylene. In VAE, the vinyl acetate content is generally higher than in EVA, typically ranging from 10% to 60% by weight. VAE is often used as a binder or adhesive in construction materials such as paints, coatings, adhesives, and textiles.
So, while both EVA and VAE are copolymers of ethylene and vinyl acetate, they have different compositions and applications.
