Unidirectional polyimide film is a high-performance insulating material, which has excellent high temperature resistance, chemical corrosion resistance, radiation resistance and other properties, and is mainly used in the following fields:
1. electronic and electrical
Wire and cable: as an insulating layer material, it can improve the high temperature resistance and electrical insulation performance of wire and cable, and ensure safe and stable operation under high voltage and high frequency working environment. It is commonly used in aerospace, military industry and other fields with high requirements for wire and cable performance.
Motor insulation: it is used for the winding insulation of the motor, which can withstand the high temperature and electromagnetic field generated during the operation of the motor, improve the efficiency and reliability of the motor, extend the service life of the motor, and is widely used in new energy vehicle drive motor, industrial motor and other fields.
Copper clad laminate: it is one of the important materials for making printed circuit board (PCB). It can be used as insulation layer and copper foil to produce copper clad laminate with high heat resistance and good electrical performance. It meets the needs of the development of electronic equipment to miniaturization and high performance, and is widely used in electronic products such as computers and communication equipment.
2. Aerospace
Aeroengine: in the high-temperature components of aeroengine, such as combustion chamber, turbine blade and other parts, unidirectional polyimide film can be used as heat insulation and insulation material, which can withstand extreme high temperature environment, ensure the normal operation of the engine, and improve the performance and reliability of the engine.
Aircraft structural parts: used in the structural parts of aircraft, such as wings, fuselage and other parts, as the reinforcement layer or insulation layer of composite materials, it can reduce the weight of aircraft, improve the strength and high temperature resistance of structural parts, and help to improve the fuel efficiency and flight performance of aircraft.
3. new energy
Solar cell: in solar cell module, unidirectional polyimide film can be used as packaging material to protect the cell from the influence of external environment, such as moisture, ultraviolet, etc., and improve the service life and performance stability of the cell module.
Lithium ion battery: as the separator material or insulating coating of lithium-ion battery, it can prevent the internal short circuit of the positive and negative electrodes of the battery. At the same time, it has good ion conductivity and chemical stability, which helps to improve the charging and discharging efficiency and safety of the battery. It has important applications in electric vehicles, energy storage power stations and other fields.
