EVA is a copolymer of ethylene and acetic acid. Chinese chemical name: ethylene-vinyl acetate copolymer (ethylene-vinyl acetate copolymer), English chemical name: Ethylene Vinyl Acetate Copolymer. The application field of EVA is quite extensive, and the annual market consumption in China is constantly increasing, especially in the shoe industry, which is used in the soles and interior materials of high-end sneakers, hiking shoes, slippers, sandals.

Ethylene-vinyl acetate copolymer, referred to as EVA. Generally, the content of vinyl acetate (VA) is 5%-40%. Compared with polyethylene (PE), EVA reduces the high crystallinity and improves the toughness and impact resistance by introducing vinyl acetate monomer into the molecular chain. , filler compatibility and heat sealing performance, is widely used in foaming shoes, functional shed film, packaging mold, hot melt adhesive, wire and cable and toys.
