Ethylene Vinyl Acetate (EVA) Plastics are copolymers of ethylene and vinyl acetate. It’s an extremely elastic material that can be processed like various thermoplastics. Normally, this thermoplastic resin is copolymerized with other resins like LDPE and LLDPE or it’s a part of a multilayer film. This material has low-temperature toughness and UV Radiation resistance. Forms of EVA include high density, medium density, and low density. The weight percent of vinyl acetate is generally between 10 to 40% and the rest is ethylene. The higher the VA content the more rubber-like the EVA resin is.
EVA is widely used for injection, extrusion, compression and blow molding processes. EVA materials can also be used as sealants in meat and dairy packaging structures, footwear, wire, and cable insulation, medical packaging, etc. Its main characteristics include good flexibility, good transparency, good impact strength and superior ECSR.
