TPE二次注塑(包胶)粘结不好，一定是料的问题?
包胶是TPE的重要应用，塑伯经常遇到用户咨询TPE包胶粘不好的问题。一些用户第一时间会怀疑定是料出了问题。当然，包胶粘不好，是料的问题这种可能性一定有的，但其次也可能是客户注塑成型采用的温度不够所致。不同的TPE材料以及包胶的硬塑料不同，模具及产品结构等，都会作为成型温度设定要考虑的因素。

|
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. |
