eva copolymer, EVA for short. General (VA) content in 5%-40%, compared with polyethylene PE, EVA due to the introduction of va monomer in the molecular chain, thereby reducing the high degree of crystallization, improve toughness, impact resistance, filler phase compatibility and thermal sealing performance, is widely used in foam footwear, functional shed film, packaging mold, hot melt adhesive, wire and cable and toys and other fields.
