Ethylene Vinyl Acetate

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

1) EVA with VA content below 5%, its main products are film, wire and cable, LDPE modifier, adhesive, etc.

2) EVA with VA content of 5%~10%, the products are elastic film, injection molding and foaming products, etc.

3) EVA with VA content 20%~28% is mainly used for hot melt adhesives and coating products.

4) EVA with VA content 28%-33%, photovoltaic materials, solar cell adhesives, etc.

5) EVA with VA content 38%-40%, adhesive.

6) EVA with VA content in 5%~45%, the main products are film (including agricultural film) and sheet, injection, molding products, foaming products, hot melt adhesive, etc.
