剪切和拉伸流动的机械加工,在变相过程中,实现的热分解的程度的原料。是必要的,以确保每一个部分的同样程度的处理,这样可避免某些部分不搅拌剪切力导致最终产生斑点和凝胶材料。通过TPE剪切和拉伸流动研究表明,热塑性弹性体具有相似的相对粘度,将有利于驱散。当一个临界值以上毛细血管的数量,只要简单的剪切流动,可以达到良好的分散。当然,实验证明,,使用拉伸流动,可以更好地实现分散。橡胶高弹性,高强度,高弹性,但也有注塑加工的特征,环保无毒安全,硬度范围广,优良的着色性,触感柔软,耐候性,耐疲劳性和耐温性优越的加工性能,不固化,可以循环使用,以降低成本,无论是二次注塑

注意事项Matters need attention
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5%.
Consistent regrind usage of up to 5% is permissible.
