EVA, known as ethylene-vinyl acetate copolymer, is obtained by polymerizing ethylene and vinyl acetate. As the vinyl acetate content increases, the density increases while the crystallinity decreases, resulting in increased flexibility. Low-density EVA, similar to regular low-density polyethylene, is often used in various applications such as cushioning materials and adhesive for laminated films due to its excellent impact resistance, especially at low temperatures, and superior resistance to stress cracking.
