简      介：

1972年美国GE公司开始研究开发PEI，经过10年时间试制、试用，于1982年建成5000吨生产装置，并正式以商品ULTEM在市场销售。

特      性：

具有优良的机械性能、电绝缘性能、耐辐照性能、耐高低温及耐磨性能，并可透过微波。加入玻璃纤维、碳纤维或其他填料可达到增强改性的目的。也可和其他工程塑料组成耐热高分子合金，可在-160~180℃使用。

PEI 聚乙醚

    典型应用范围:

    汽车工业（发动机配件如温度传感器、燃料和空气处理器等），电器及电子设备（电气联结器、印刷电路板、芯片外壳、防爆盒等），产品包装，飞机内部设备，医药行业（外科器械、工具壳体、非植入器械）。

    注塑模工艺条件:

    干燥处理：PEI具有吸湿特性并可导致材料降解。要求湿度值应小于0.02%。建议干燥条件为150C、4小时的干燥处理。

    熔化温度：普通类型材料为340~400C；增强类型材料为340~415C。

    模具温度：107~175C，建议模具温度为140C。

    注射压力：700~1500bar。

    注射速度：使用尽可能高的注射速度。

    化学和物理特性:

    PEI具有很强的高温稳定性，既使是非增强型的PEI，仍具有很好的韧性和强度。因此利用PEI优越的热稳定性可用来制作高温耐热器件。PEI还有良好的阻燃性、抗化学反应以及电绝缘特性。玻璃化转化温度很高，达215C。PEI还具有很低的收缩率及良好的等方向机械特性。
