EVA（乙烯-醋酸乙烯共聚物）的加工温度范围一般在130°C至180°C之间‌。这个温度范围确保EVA能够熔化成液态，具有流动性，方便进行各种加工工艺，如注塑、挤出、压延等。同时，这个温度范围能够保持EVA的物理性能和化学稳定性，避免其发生分解或降解。‌

不同加工方法的具体温度要求

‌注塑‌：EVA注塑温度通常在100-120度到140-160度之间，具体温度取决于EVA的熔点高低。

‌挤出‌：挤出温度一般在160-200℃之间。

‌压延‌：压延温度也在160-200℃之间。

EVA材料的特性

EVA具有良好的柔软性、抗冲击强度、耐低温性和耐环境应力开裂性能，同时具有良好的光学性能、化学稳定性、抗老化和耐臭氧强度。此外，EVA还具有无毒无害的特性。这些特性使得EVA在加工过程中需要控制适当的温度以保持其物理性能。
