 EVA
     
EVA的化學品中文名稱是乙烯-醋酸乙烯共聚物,ethylene-vinyl acetate copo 的簡稱。EVA的用處很多,一般用在製造防凍食品袋、各種拉仲膜、夾心板(擠壓膜)、溫室膜和各種農業生產用膜、高強耐破裂袋等地方 。除了上面的說的地方,EVA由於其自身具有有良好的發泡性能和優異的回彈耐老化性、輕量性,因而廣泛用於如化妝品內襯、工具箱內托、防護防撞條、鞋墊、童車輪、隔音板、汽車零部件、緩踏板、體操墊、遊艇防護板等地方。
 

 

EVA材料性能:


耐水性:密閉泡孔結構,不吸水,防潮,耐水性能良好。
 

耐腐蝕:耐海水、油脂、酸、鹼等化學品腐蝕,抗菌、無毒、無味、無污染。


防震性:回彈性和抗張力高,韌性強,具有良好的防震、緩衝性能。


保溫性:隔熱,保溫防寒及低溫性能優異,可而嚴寒和曝曬。


隔音性:密閉泡孔,隔音效果好,有效降低音量分貝。


加工性:易於裁剪,衝壓、熱壓,分切,成型,背膠,貼合,膠墊等加工。
