Ethylene vinyl acetate (EVA)

Due to their high versatility in hot-melt formulations, EVAs are leading polymers for hot-melt manufacturing. EVA based hot-melts are able to fulfill various requirements in applications such as packaging, bookbinding or label sticking. They are highly flexible products, compatible with many other polymers and additives, and are easy to process. Due to its chemical structure, the EVA range: are highly flexible delivers high cohesive strength and compatibility ensures excellent adhesion to a wide range of substrates are highly resistant to rupture Thanks to their high compatibility, they can be formulated in combination with both natural or synthetic tackifiers, a large range of PE waxes, modified waxes or plasticizers and their intrinsic stability can be enhanced by the right choice of antioxidant or UV/Light stabilizers; See below the structure of random Ethylene Vinyl Acetate copolymers obtained by high pressure radical polymerisation: Figure 1 : Structure of random Ethylene Vinyl Acetate copolymers
