Only when the content of vinyl acetate in EVA is less than 20% can it be used as plastic. EVA plastic raw materials are very good Low temperature resistance, with a lower thermal decomposition temperature of about 230 ℃. As the molecular weight increases, the softening point of EVA increases, Processability and surface gloss of plastic parts decrease, but strength increases, impact toughness and environmental stress cracking resistance improve, and EVA is resistant to weathering Compared to PE and PVC, the drug resistance and oil resistance are slightly worse, and the changes are more pronounced with the increase of vinyl acetate content.
