EVA has improved performance compared to PE, mainly in terms of elasticity, flexibility, glossiness, breathability, etc. In addition, its environmental stress resistance is also improved The crack resistance has been improved, and the tolerance of the filler has increased. The method of adding more reinforcing fillers can be used to avoid or reduce EVA The decrease in mechanical properties compared to PE. EVA can also be modified to obtain new applications, and its modification can mainly be considered from two aspects. One is to use EVA as the backbone for grafting other monomers; The second is to partially alcoholize EVA.
