Description
A thermoplastic, elastomeric copolymer. Ethylene vinyl acetate copolymers (EVA) are commonly used in packaging applications replacing Polyvinyl chloride as the most used resin. EVA copolymers require no curing or Plasticizer and have no odor. They can be molded and extruded into many shapes and are available as films, sheeting and tubing. EVA copolymers are clear, tough, crack resistant and retain flexibility at low temperatures. Depending on the proportions of each polymer, EVAs soften at about 70C. They are used in paper coatings, shrink-wrap, and hot-melt adhesives. As hot melts, EVAs have been used in the fabrication of storage and travel cases (Hatchfield 2002).
