PEI一指 polyetherimide (PEI), is color transparent solid 体, add additives has solid has flame retardant property and low degree, oxygen index (LOI) is 47%, and other grade is UL 94-V-0 grade, density is 1.28~1.42g/cm3. PEI tool has very strong/high high temperature stability property, make is non reinforcement type PEI, still tool has very good tough property and strong/high degree. therefore utilizing PEI excellent heat stabilized property can use made as high temperature heat resistant device parts. tool has excellent mechanical properties, electrical insulation property can, resistant property can, resistant high low temperature and wear resistance can, can micro 波. PEI also has good flame retardant property, resistant chemical reaction and electrical insulation features. 玻璃化转化 temperature degree very high, 达215℃. PEI also tool has very low shrinkage rate and good and other direction machine features. add glass fiber, carbon fiber or other filler can to reinforcement modified 目;也 can and its it engineering plastics formed heat resistant polymer/macromolecule alloy, can in -160~180℃ 工 as temperature degree lower long use.

一, PEI key features

1, PEI in 文名字(polyetherimide (PEI)) is color transparent solid 体, has good flame retardant property and low degree,燃烧 and other grade is UL 94-V-0 grade.

2, PEI tool has very strong/high high temperature stability property. high temperature resistance, heat deflection temperature (HDT) 达220℃, can in -160一180℃ 工 as temperature degree lower long use.

3, hydrolysis stability property very good, high temperature resistance, resistant 蒸汽;

4, polyetherimide (PEI) tool has very good UV resistant, Y射线 property can.

二, application

due to PEI tool has excellent comprehensive balanced property can, has formed 效 应 used for electronics, electrical machine and aviation and other industrial 部门, used as product and 文化生 active use product metal use material. use PEI取代 metal manufacturing light connectors, can make parts structure most 佳化, its manufacturing and assembly steps, maintain more dimensions. used for automotive field/area, use manufacturing high temperature parts, high rate and 指示灯, control automotive external temperature degree device (空调 temperature degree device) and control gas and material mixed combined material temperature degree device (has 效燃烧 temperature degree device). also can used as high temperature resistance lubricated 油侵蚀 true 空泵叶轮, in 180℃操 as device abrasion 口玻璃接头(承接口), non lighting anti 雾灯 反射镜.
