TPE材料微观结构决定了其性能,决定了其在塑胶界特殊的地位和作用。
1、TPE材料结构中不含不饱和键,性质比较稳定,具有良好的耐温(使用温度范围-50-100℃),耐老化,耐化学性,耐溶剂性。
2、TPE材料结构中含有常温为玻璃态的乙烯-苯乙烯刚性链段,赋予材料固定的形状,保证使用性能;材料结构中含有常温为高弹态的丁二烯柔性链段,赋予材料舒适的柔软触感及弹性。
3、TPE材料在生产过程中不引入重金属,不添加有毒的邻苯二甲酸盐增塑剂,符合ROHS、REACH、EN71、PAHS及FDA环保检测。
4、TPE材料采用直接注塑成型,加工容易,成型周期短,废制品回收容易,是取代橡胶及硅胶的理想材料。
5、TPE材料通过配方及配比的变化,可提供物性及硬度多样化的材料,以符合不同产品宜的使用要求。

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. |
