TPE和TPR又有什么区别
TPE与TPR同属热塑性弹性体，目前弹性体业界尚无界定的标准。广义的说TPE和TPR都是弹性体的通称，没什么区别。但从TPE业界狭义的角度来定义，TPE与TPR还是有一定的区别。
TPE是其英文名Thermoplastic Elastomer的缩写，意思是热塑性弹性体。TPR是其英文名Thermoplastic rubber的缩写，意思是热塑性橡胶。
TPE一般是以SEBS为基材改性而成，TPR一般是以SBS为基材改性而成。
而SEBS是SBS氢化（所谓氢化是指不饱和分子在特殊的反应条件下，分子中引入氢原子，从而使分子结构达到饱和状态）后的产物。SEBS具有饱和分子结构，其耐老化，耐黄变，耐温，耐腐蚀性能则优于SBS.同样的TPE的相关性能则优于TPR，

|
清洗料管 Purge compound |
需使用PP或 PE清洗干净机台螺杆，且把机台射嘴彻底清除干净Please make sure you that you have cleaned the machine screw with PP or PE, and put the machine nozzle thoroughly clean. |
|||||||
|
着色 Coloring
|
请选择以PE或EVA为基材之色母，切勿使用以PVC为基材者。另外加工时请采用较高的螺杆转速和较高的背压，才能让着色剂达到较好的分散效果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）回收比率建议最多20%. Consistent regrind usage of up to 20% is permissible. |
