EVA(乙烯·醋酸乙烯酯共聚物)

- 產品資訊 -
 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。
