长期供应PEI AR9300 SABIC

特性

（1）PEI的特点是在高温下具有高的强度、高的刚性、耐磨性和尺寸稳定性。（2）PEI是琥珀色透明固体，不添加任何添加剂就有固有的阻燃性和低烟度，氧指数为47%，燃烧等级为UL94-V-0级。（3）PEI的密度为1.28~1.42g/cm3，玻璃化温度为215℃,热变形温度198~208℃,可在160~180℃下长期使用,允许间歇使用温度为200℃。（4）PEI具有优良的机械强度、电绝缘性能、耐辐射性、耐高低温及耐疲劳性能和成型加工性；加入玻璃纤维、碳纤维或其他填料可达到增强改性目的。

PEI一指聚醚酰亚胺（Polyetherimide），它还指的是人员效率指标。 PEI （聚醚酰亚胺）是琥珀色透明固体，不添加任何添加剂PEI原料颗粒图片就有固有的阻燃性和低烟度，氧指数为47%，燃烧等级为UL94-V-0级，密度为1.28~1.42g/cm3。PEI具有很强的高温稳定性，即使是非增强型的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。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。
