单独成型的TPE材料,在同样体系的前提下,自然是弹性越佳、耐候性越好、透明度越高、加工稳定性越好,这样的材料肯定就越好,但是如果是包胶的TPE材料,你只强调这些性能不对了,因为还有一个很重要的包胶效果需要衡量。
一个其它性能都非常出色的材料,但是它包胶包不住,这就绝对不能算是个好材料,而相反,如果包胶效果不错,为此而牺牲一些其它物理性能(比如弹性),它还是一款很出色的材料,当然在包胶效果都很好的前提下,其它性能越好越能证明这个材料更出色,不过只是为了包胶效果好而牺牲了其它大部分的物理性能,这肯定也是一款不合格的材料。

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
