Chemical Composition of EVA Pellets

EVA granules are a polymer compound formed by the copolymerization of ethylene (E) and vinyl acetate (VA). Ethylene is a colorless, odorless gas with excellent chemical stability, while vinyl acetate is a colorless liquid with an acetic odor. The copolymerization of these two substances creates EVA granules with unique properties. The vinyl acetate content in EVA granules significantly influences their performance. Generally speaking, a higher vinyl acetate content results in improved EVA granule flexibility, impact resistance, transparency, and adhesion.
