tpe材料，又名熱塑性彈性體，是一種兼有塑料和橡膠特性，在常溫下顯示橡膠的高彈性，高溫下又能塑化成型的高分子材料（不需要硫化）。熱塑性彈性體的結(jié)構(gòu)特點是由化學(xué)鍵組成不同的樹脂段和橡膠段，樹脂段憑借鏈間作用力形成物理交聯(lián)點，橡膠段是高彈性鏈段，貢獻彈性。塑料段的物理交聯(lián)隨溫度的變化而呈可逆變化，顯示了熱塑性彈性體的塑料加工特性。因此，熱塑性彈性體具有硫化橡膠的物理機械性能和熱塑性塑料的工藝加工性能，是介于橡膠與樹脂之間的一-種新型高分子材料，常被人們稱為第三代橡膠。

| 清洗料管 Purge compound | 需使用PP或 PE清洗干凈機臺螺桿，且把機臺射嘴清除干凈Please make sure you that you have cleaned the machine screw with PP or PE, and put the machine nozzle thoroughly clean. | |||||||
| 著色 Coloring
| 請選擇以PE或EVA為基材之色母，切勿使用以PVC為基材者。另外加工時請采用較高的螺桿轉(zhuǎn)速和較高的背壓，才能讓著色劑達到較好的分散效果Please select color master batch on PE or EVA material with the exception of PVC.Higher screw speed and backpressure are needed for better colorant dispersion. | |||||||
