TPR DA7520 TPR包胶abs 高耐磨 握把原料 厂家直销 智能穿戴
玩具工仔选择TPE材料的优势:
1.更为环保:TPE,TPR相对于PVC而言不含邻苯二甲酸酯类塑化剂,不含卤素,材料燃烧不释放二恶英及其他有害物质。
2.加工特性.流动特性,总体而言TPE,TPR流动性要差于PVC,TPE,TPR的塑化及成型温度要高于PVC。
3.TPE,TPR可采用注塑、挤出及吹塑成型;PVC可采用注塑、挤出、搪塑(搪胶)及滴胶(滴塑,微量射出)成型。
4.硬度的表述:PVC硬度单位为P(以增塑剂的含量来表示),TPE,TPR硬度单位为A(以邵氏硬度计A测的数据来度量)。P和A,两种硬度,有一个近似的换算关系。
5.耐低温性:TPE,TPR与PVC相比,具有更佳的耐低温性,即TPE,TPR在低温-40℃不变硬,PVC在-10℃会发硬。

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 and needed for better colorant dispersion |
