Areas of application for PEI (polyetherimide).
Applications of PEI polyetherimide plastics
PEI has excellent performance and has a broad market in industries such as communications, automotive, aerospace and medical.
1. Communications
PEI material is used as optical fiber connector for optical communication, optical transceiver module optical components, RF connector insulator, base station cavity filter plastic cavity, filter tuning screw, antenna internal fixing screw, annular phase shifter bracket, etc., in addition, foamed PEI material also has advantages in millimeter wave radome.
2. Aerospace
PEI can be used in aerospace, such as air and fuel valves, food tray containers, steering wheels, interior cladding, and various structural components. PEI one-way with usable seat frame and luggage compartment etc.
3. Cars
PEI can be used in control valves, oil pumps, lights, lidars, fenders and other components of automobiles, and PEI film can be used as a high-temperature dielectric film for capacitors.
4. Medical field
PEI can be used in medical devices. Such as ventilators, anesthesia machines, sterilization trays, surgical guides, pipettes and laboratory animal cages, etc.
In addition, PEI is also used in home appliances, microwave ovens, dinner plates, and eyeglass frames. It can be seen that PEI is indeed a powerful and versatile material, and this material technology still needs to be developed in China, and there is still a long way to go to catch up with the international level, let us wait and see.
