热塑性弹性体如今应用越来越广泛了，除了应用在汽车等工业外，下面为大家介绍：热塑性弹性体作为医用材料所必须满足的条件是什么
医用材料要与人体组织、血液、体液等接触，有的甚至永久性植入体内。因此，这类材料必须具有优良的生物体可替代性（力学性能、功能性）、生物相容性和血液相容性。热塑性弹性体同样需满足下列基本条件：
(1)在化学上是惰性的，不会因与体液接触而发生反应；
(2)对人体组织不会引起炎症和异物反应；
(3)不会致癌；

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. |
|||||||
|
回收 Recycling |
二次料（水口料）回收比率建议最多10%. Consistent regrind usage of up to 10% is permissible. |
