Common Characteristics of EVA EVA EVA in less than 20% of vinylacetate content, then can be used as a plastic. Eva has a good lowtemperature resistance, its thermal decomposition temperature islower, about 230 °C. With the increase of molecular weight, Eva'ssoftening point rises, the workability and the surface gloss ofplastic parts decrease, but the strength increases, the chemicaland oil resistance of EVA is slightly worse than that of Pe andPVC, and the change is more obvious with the increase of thecontent of Vinyl Acetate. The performance of Eva is better than PE,mainly in elasticity, flexibility, gloss, permeability, etc. . Inaddition, its resistance to environmental stress cracking isimproved, and its acceptance of fillers is increased, the decreaseof mechanical properties of Eva compared with PE can be avoided orreduced by adding more reinforcing fillers. The modification of EVAcan be considered from two aspects: one is to graft EVA onto othermonomers, the other is to partially alcoholysis Eva.
