EVA material is plastic or rubber?
Is a relatively common in bottom material, usually called a foam have buffer action, but this material is very slippery, so the general and hard rubber mixed with EVA, is a kind of common material in many sports shoes are in effect but it is difficult to compete with the AIR.
EVA resin is a copolymer of ethylene vinyl acetate, ethylene vinyl acetate (VA) content in 5% ~ 40%. compared with polyethylene, EVA in molecular chain was introduced in vinyl acetate monomer, thereby reducing the high crystallinity, improved flexibility, impact resistance, filler compatibility and heat sealing performance, is widely used in the foaming shoes material, functional films, packaging film, hot melt adhesive, wire and cable and toys and other fields.
