PEI常见问题

1．PEI塑料对成型加工设备有何要求？

答：聚醚酰亞胺PEI流动性较好。它具有低熔融粘度和好的流动性, 可用典型的热塑性塑料熔融加工工艺和设备制造成型件。但由于PEI成型加工条件较高，故对提供较高要求（330℃-380℃）。

2．PEI塑料制品较脆主要是什么原因？

答：聚醚酰亞胺PEI为非结晶材料，故表现出良好的韧性；一般来说一些客户反馈制品较脆主要是由于成型过程中，故发脆的制品总是伴随着制品表面出现银纹。

3．PEI塑料制品表面为什么出现明显的银纹？

答：PEI制品表面出现银纹可能一些客户会认为是PEI材料没有烘干，故长时间烘料。而根据我们的经验，PEI塑料（无论新料还是回料）一般烘150℃/5小时左右即可。制品表面出现银纹主要是由于PEI材料加工温度过高出现分子链。这一点可以通过对空射胶来判断和体现。

4．PEI塑料制品有时出现不易射满，射满又出现，一般该如何解决？

答：PEI塑料虽然流动性较好，但该材料成型有一个比较独特的特点：。故需要在模具设计和调整注塑成型工艺时充分考虑到PEI塑料这一特点（正是PEI成型制品冷凝特别快，所以PEI制品很少出现缩痕明显的情况）。一些客户为了注满模腔，于是开始提高料温从而导致材料降解（为敏感）制品表面出现银纹。

具体解决方法：① 提高模具温度，使制品缓慢冷凝；② 改进模具流道，确保融体快速均匀注入模具型腔；

5．PEI塑料优越性能主要表现在哪几个方面？

答：① PEI材料, 介质损耗因数较低, 且其电气性能随温度升高变化很小, 特别是高温下的介电常数较低, 是较理想的电子电气绝缘材料。 ② PEI 的力学性能优良, 室温下有较高的拉伸强度和弯曲强度, 高温下；③相对其他聚酰亚胺材料如PI、PAI等）来讲，ULTEM PEI价格相对低得多，表现出良好的xxx；④ ULTEM PEI材料表现出良好的（当然电镀性能好坏还与制品的成型质量有很大关系）；

6．PEI塑料制品正常的外观应该如何？

答：正常来说PEI制品表面光滑、无银纹、银丝
