TPE注塑级 -BS505 厂家直销 tpe原料 透明水管软管
TPE只是一类材料?价格较固定?
有些用户,一打过来就问,你家TPE多少钱一吨。似乎TPE就是那么一种材料,而且性能比较固定,价格也比较固定一样。可实际上,TPE包含很多种类型,如TPU,TPV,TPEE,以及基于SEBS,SBS基材的TPR(TPE). TPE种类较多,非一种材料,价格自然不能随意报价。
另外顺便提及,通常说的TPE,大多指SEBS基础改性的弹性体TPE,这类TPE也有不同的硬度和物性,价格也应根据客户要求来评估。

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. |
