EVA乳液
EVA乳液是醋酸乙烯－乙烯共聚乳液的简称，是以醋酸乙烯和乙烯单体为基本原料，与其它辅料通过乳液聚合方法共聚而成的高分子乳液。
EVA乳液主要用于胶粘剂、涂料、水泥改性剂和纸加工，具有许多优良的性能。
EVA乳液具有的柔韧性。EVA乳液可以看作是聚醋酸乙烯乳液的内增塑产品，由于它在聚醋酸乙烯分子中引入了乙烯分子链，使乙酰基产生不连续性，增加了高分子链的旋转自由度，空间阻碍小，高分子主链变得柔软，并且不会发生增塑剂迁移，保证了产品性柔软。
EVA乳液具有较好的耐酸碱性。EVA乳液在弱酸和弱碱存在条件下均能够保持稳定性能，因此它不论与弱酸或弱碱混合都不会发生破乳现象，产品应用范围较广。
EVA乳液能够耐紫外线老化。由于EVA乳液是采用乙烯作为共聚物的内增塑剂，使EVA聚合物具有内增塑性，增塑剂不会发生迁移，从而避免了聚合物性能老化。因此，不仅是EVA乳液对紫外线有很好的稳定性，就是EVA乳液成膜后同样也可保持这一特点。
EVA乳液具有良好的混容性。EVA乳液能与大多数添加剂混合，如分散剂、润湿剂、防冻剂、消泡剂、防腐剂、阻燃剂等，因而可以满足各种不同需要；EVA乳液能与许多颜料和填料混合，而不会发生凝聚现象
