PEI的特性以及在塑料产品中的应用

PEI：聚醚酰亚胺窗体顶端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。

由于因为PEI 兼具优良的高温机械性能和耐磨性，故可用于制造输水管转向阀的阀件。由于具有很高的强度、柔韧性和耐热性，是优良的涂层和成膜材料，能形成适用于电子工业的涂层和薄膜。主要特点连续工作温度范围大（-200--170度长期工作）玻璃化温度与热变性温度接近、熔点高达330度 在低温/高温下仍保有高机械强度、高硬度、高抗蠕变性、良好韧性杰出的抗析出性。

所以PEI应用广泛，主要应用于电子行业：连接件、普通和微型继电器外壳、电路板、 线圈、软性电路、反射镜、高精度密光纤元件、高温隔热板 。汽车行业：连接件、高功率车 灯和指示灯、控制汽车舱室外部温度的传感器、控制空气和燃料混合物温度的传感器，医疗器材等。

Characteristics of PEI and in application of plastic products:

PEI: poly-ether imide with excellent mechanical properties, electric insulation properties, high radiation resistant, good resistance to low temperature and wear resistance, which is accessible via microwave.

As PEI both excellent high-temperature mechanical properties and wear resistance, steering valves can be used in the manufacture of water pipe valves and fittings. Due to its high flexibility and strength, heat resistance, is an excellent coating and film-forming material, and they can apply in the electronics industry coatings and thin films.

Main characteristics of continuous operating temperature range (long-term exercise -200--170) glass transition temperatures and thermal denaturation temperature close, up to 330 degrees at low/high temperature melting point has maintained high mechanical strength, high hardness, high outstanding resistance to creep resistance, good toughness of precipitation.

So PEI widely used, mainly used in the electronics industry: Shell connectors, General and micro-relays, circuit boards, coils, soft circuits, secret mirror, high precision optical components, high-temperature insulating Board. Automotive industry: connectors, high power lights and indicator lights, control of vehicle cabin external temperature sensors, control of air and fuel mixture temperature sensor, medical equipment and so on.
