Applications and features:
Ethylene-vinyl acetate (EVA) copolymers are used in extrusion film processes for applications including packaging, surface protection, and greenhouse covers, and in photovoltaic cell encapsulation. EVA copolymers are used in molded caps and seals, footwear, and car interiors. They are the base polymer in many adhesive resin formulations and in wire and electrical cables compounding. For the hot-melt adhesive needed to hold pages and covers together in bookbinding applications, low to medium MI and high VA grades are used to maximize cohesive strength and flexibility. EVA is an elastomeric polymer that produces materials that are “rubber-like” in softness and flexibility. The material has good clarity and gloss, low-temperature toughness, stress crack resistance, hot-melt adhesive waterproof properties, and resistance to UV radiation. EVA has a distinctive vinegar-like odor and is competitive with rubber and vinyl polymer products in many electrical applications.
