TPE原料 DT5013 厂家直销水壶手柄包胶料水管软管 智能穿戴
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。

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 |
