EVA-18% TO 25%-APC-EV303
| 特性 | Characteristics | |||
| EV303 是一種乙烯醋酸乙烯酯共聚合樹脂，具有很多優異特性，包括：柔軟而有彈性，透明、無毒， 抗外界應力龜
裂性很強，抗衝擊強度高，低溫柔軟性很好，以及加工容 易等，所以可用以開發新用途，及替代軟質 PVC、橡膠與其他彈性材料。 EV303 可添加發泡劑、交聯劑及無機填充物， 以射出或壓縮成型法製造發泡中底。膜片擠壓加工，如鑄膜擠壓及共 擠壓的成品，可作醫療與醫藥材料的特殊包裝，及食品的
裹包與包裝之用。 |
POLYMER-E ®® EV303 is the ethylene vinyl acetate copolymer resin(EVA), possessing many excellent characteristics including flexibility, elasticity, transparency, non-toxicity, good resistance to
environmental stress cracking, low temperature flexibility, good processability, etc. For these characteristics, The POLYMER-E ®® EV303 can be used to develop the new applications and replace the flexible PVC, rubbers and other elastomers. One of the applications is the incorporation of foaming agents, crosslinking agents and inorganic fillers with POLYMER-E ®® EV303 for injection and compression molding of foamed mid-sole material for shoes. POLYMER-E ®® EV303 is extruded to sheet such as casting and co-extrusion for special packaging of hospital and medical materials, food packaging and other packaging. |
