TPE材料微觀結構決定了其性能，決定了其在塑膠界特殊的地位和作用。
1、TPE材料結構中不含不飽和鍵，性質比較穩定，具有良好的耐溫（使用溫度范圍-50-100℃），耐老化，耐化學性，耐溶劑性。
2、TPE材料結構中含有常溫為玻璃態的乙烯-苯乙烯剛性鏈段,賦予材料固定的形狀，保證使用性能;材料結構中含有常溫為高彈態的丁二烯柔性鏈段，賦予材料舒適的柔軟觸感及彈性。
3、TPE材料在生產過程中不引入重金屬，不添加有毒的鄰苯二甲酸鹽增塑劑，符合ROHS、REACH、EN71、PAHS及FDA環保檢測。
4、TPE材料采用直接注塑成型，加工容易，成型周期短，廢制品回收容易，是取代橡膠及硅膠的理想材料。
5、TPE材料通過配方及配比的變化，可提供物性及硬度多樣化的材料，以符合不同產品宜的使用要求。

| 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. |
