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,

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20%.
Consistent regrind usage of up to 20% is permissible.
