EVA has good low-temperature resistance, with a lower thermal decomposition temperature of about 230 ℃. With the increase of molecular weight, the softening point of EVA increases, and the processability and surface gloss of plastic parts decrease. However, the strength increases, and the impact toughness and environmental stress cracking resistance are improved. The chemical and oil resistance of EVA is slightly worse than that of PE and PVC, and the changes become more obvious with the increase of vinyl acetate content.
The performance improvement of EVA compared to PE is mainly in terms of elasticity, flexibility, glossiness, breathability, etc. In addition, its resistance to environmental stress cracking has been improved, which increases the compatibility of fillers. The method of adding more reinforcing fillers can be used to avoid or reduce the decrease in mechanical properties of EVA compared to PE. EVA can also be modified to obtain new applications, and its modification can mainly be considered from two aspects: first, using EVA as the backbone for grafting other monomers; The second is to partially alcoholize EVA.
