What Is EVA?

EVA referred to Ethylene-vinyl acetate copolymer. Generally, the content of vinyl acetate (VA) is 5%-40%. Compared with polyethylene (PE), EVA introduces vinyl acetate monomer in the molecular chain, thereby reducing high crystallinity, improving toughness, impact resistance, filler compatibility, and heat sealing properties. EVA is widely used in foam shoe materials, functional shed films, packaging molds, hot melt adhesives, wires and cables, toys, and other fields.

Is EVA Toxic?

EVA is non-toxic and environmentally friendly.

The Characteristics of EVA

●good cushioning

●heat insulation

●moisture resistance

●chemical corrosion resistance

●non-toxic

●non-absorbent

●certain toughness

●easy hot pressing

Applications

EVA resin has a wide range of applications. In general, according to the proportion of vinyl acetate content, it can be divided into the following uses:

▶VA content below 5%

films, wires, and cables, LDPE modifiers, adhesives, etc.;

▶VA content of 5%-10%

elastic film, injection molding, foaming products, etc.;

▶VA content of 20%-28%

mainly used for hot melt adhesives and coating products;

▶VA content of  28%-33% 

photovoltaic materials, solar cell adhesives, etc.;

▶VA content of 38%-40%

adhesive;

▶VA content of 5%-45%

films (including agricultural films) and sheets, injection molding, molded products, foamed products, hot melt adhesives, etc.
