Common Characteristics of EVA EVA EVA in the content of vinylacetate less than 20% , then can be used as a plastic. Eva has goodlow temperature resistance and its thermal decompositiontemperature is about 230 °c. with the increase of the molecularweight, the softening point of Eva increases, the workability andthe surface gloss of the plastic parts decrease, but the strengthincreases, the chemical resistance and oil resistance of Eva areslightly worse than those of Pe and PVC, and the change is moreobvious with the increase of the content of Vinyl Acetate. Theperformance of EVA is improved than PE, mainly in the aspects ofelasticity, flexibility, gloss, permeability, etc. . In addition,its resistance to environmental stress cracking is improved, andits acceptance of fillers is increased, the decrease of mechanicalproperties of Eva compared with PE can be avoided or reduced byadding more reinforcing fillers. The modification of EVA can beconsidered from two aspects: one is to graft EVA onto othermonomers, the other is to partially alcoholysis Eva.
