About Ethylene Vinyl Acetate. Ethylene Vinyl Acetate (a.k.a. EVA) is the copolymer of ethylene and vinyl acetate. EVA properties vary depending on the comonomers contents. Vinyl acetate increases gas permeability, impact strength, crystallinity, coefficient of friction and optical qualities. Meanwhile, higher ethylene content increases sealing temperature, stiffness and surface hardness. As a thermoplastic, EVA is capable of melting and flowing (in a reversible physical transformation) when subjected to increases in temperature and pressure, assuming a specified form when those conditions cease. Exhibiting properties like good toughness, flexibility, clarity and gloss, this thermoplastic material is one of the most important poly(vinyl esters).
Chemical Formula. (C2H4)n(C4H6O2)m
Commercial Grades. Grades very in vinyl acetate content, between 7.5 and 40 wt%
Uses. As previously mentioned, EVA is produced in a range of grades, according to the intended applications. In general, EVA with very low vinyl-acetate content (approximately 3 mole percent), essentially a modified low-density polyethylene, is used as a film due to its flexibility and surface gloss. EVA with approximately 11 mole percent vinyl acetate is widely used in the hot-melt coatings and adhesives, while EVA with 15 mole percent vinyl acetate present similar mechanical properties to plasticized PVC. Other major application for EVA are: fire-resistant cable insulation; hot melt adhesives; roof covering membranes; hot melt/packaging adhesives; pour point depressant (lubricants); wax additive; latex adhesives; latex binder; latex coatings/dressings/textile auxiliaries; rubber shoesoling/flexible gaskets/tubing/ toys; heavy sacking film; shrink/ heat-sealing film; stretch film (food packaging).
