PEI性能介绍:
PEI聚醚酰是琥珀色透明固体,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。PEI聚醚酰,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,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。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215℃。PEI还具有很低的收缩率及良好的等方向机械特性。加入玻璃纤维、碳纤维或其他填料可达到增强改性的目的;也可和其它工程塑料组成耐热高分子合金,可在-160~180℃的工作温度下长期使用。美国保险商实验室规定聚醚树脂的长期使用温度是338T和356T根据等级,燃烧等级达到UL94V—010密耳厚度。氧指数达47,PEI符合飞机内件要求的FAA阻燃性和热稀放性的材料标准。它的玻璃化转变温度为419F,并允许在392F下间断使用,在更高温度下,产生短期偏移。
由于PEI具有优良的综合平衡性能,卓有成效地应用于电子、电机和航空等工业部门,并用作传统产品和文化生活用品的金属代用材料。用PEI取代金属制造光纤连接器,可使元件结构化,简化其制造和装配步骤,保持更的尺寸。用于汽车领域,如用以制造高温连接件、高功率车灯和指示灯、控制汽车舱室外部温度的传感器(空调温度传感器)和控制空气和燃料混合物温度的传感器(有效燃烧温度传感器)。还可用作耐高温润滑油侵蚀的真空泵叶轮、在180℃操作的蒸镏器的磨口玻璃接头(承接口)、非照明的防雾灯的反射镜。
Pei is an excellent coating and film-forming material, which can form coating and film suitable for electronic industry, and can be used to manufacture microporous membrane with pore diameter < 0.1 μ m and high permeability. It can also be used as high temperature resistant adhesive and high strength fiber.
Pei has strong high temperature stability, even if it is non reinforced Pei, it still has good toughness and strength. Therefore, Pei can be used to make high temperature heat-resistant devices. Pei also has good flame retardant, chemical resistance and electrical insulation properties. The glass transition temperature is very high, up to 215 ℃. Pei also has low shrinkage and good isotropic mechanical properties. Adding glass fiber, carbon fiber or other fillers can achieve the pure of reinforcement and modification; it can also form heat-resistant polymer alloy with other engineering plastics, which can be used for a long time under the working temperature of - 160 ~ 180 ℃. UL stipulates that the long-term service temperature of polyetherimide resin is 338t and 356t. According to the grade, the combustion grade reaches ul94v-010 mil thickness. The oxygen index is 47, and Pei meets the FAA flame retardant and heat release material standards for aircraft internals. It has a glass transition temperature of 419f and allows intermittent use at 392f, resulting in short-term excursion at higher temperatures.
