熱塑性彈性體TPE（Thermoplastic Elastomer） 是一種具有橡膠的高彈性，高強度，高回彈性，又具有可注塑加工的特征的材料。具有環保無毒安全，應用范圍廣，有優良的著色性，觸感柔軟，耐候性，抗疲勞性和耐溫性，加工性能*，無須硫化，可以循環使用降低成本，既可以二次注塑成型，與PP、PE、PC、PS、ABS等基體材料包覆粘合，也可以單獨成型。
TPE主要的9個特征：
1、環保、無毒、無污染（有歐洲無毒標準證書）
2、不用硫化、簡化生產加工過程
3、具有優良的耐低溫、耐高溫性
4、觸感柔軟、表面質量優異
5、寬廣的硬度范圍：OA-100A
6、水口料、邊角料可循環使用
7、可依客戶之要求調整您所需求的材料
8、加工過程無毒性，更不會產生令人不愉快的氣味
9、對環境及設備無傷害

| 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. | |||||||
| 回收 Recycling | 二次料（水口料）回收比率建議最多10%. Consistent regrind usage of up to 10% is permissible. | |||||||
