TPS弹性体的主要加工成型方法
TPS类弹性体极易加工成型，常规的加工方法如注塑(包括单物料注塑成型及双物料/多物料注塑成型)，挤出，压延(淋膜)，吹塑等都可以成型，TPE 弹性体还可以熔胶成液体态，再浇注入预定的模具中，成型冷却即可。
TPE/TPR与PVC之区别比较
TPE/TPR与PVC软胶基本组成：TPE/TPR软胶，是以硬质SEBS/SBS (聚苯乙烯--丁二烯--苯乙烯嵌段共聚物)为主要基材，添加软化油，填充物及其他成分制成的功能性复合材料。
PVC软胶是以聚氯乙烯为主要基材，添加软化剂(增塑剂),抗稳定剂等其他组分，制成的具有橡胶弹性的复合软胶材料。

|
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 and 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 |
