EVA resin is ethylene vinyl acetate copolymer, and the content of vinyl acetate (VA) is generally 5% ~ 40%. Compared with polyethylene, EVA reduces the high crystallinity and improves the flexibility, impact resistance, filler compatibility and thermal sealing performance due to the introduction of vinyl acetate monomer in the molecular chain. It is widely used in the fields of foamed shoe materials, functional shed films, packaging films, hot-melt adhesives, electric cables and toys. Generally speaking, the performance of EVA resin mainly depends on the content of vinyl acetate in the molecular chain.
