Polyimide (PI) is an aromatic heterocyclic polymer compound with a molecular structure containing acyl imine chain links. It is currently one of the most heat-resistant varieties in engineering plastics and is known as the top material of the polymer material pyramid. It has a wide range of application fields, as follows:
Aerospace: Polyimide is one of the most heat-resistant structural materials and is widely used in aerospace and rocket components in developed countries such as Europe and America. Like supersonic aircraft in the United States, 50% of the structural materials are carbon fiber reinforced composite materials with plastic polyimide as the matrix resin. Polyimide foam material is inherently flame retardant, heat resistant, light in weight, environmentally friendly and non-toxic, and can be used for a long time under extreme conditions such as ultra-high temperature and strong radiation. It has been increasingly used in key materials such as heat insulation, shock absorption and noise reduction, and insulation in high-tech fields such as aerospace, ocean transportation, and national defense.
Microelectronics: Polyimide has unique application value in the field of microelectronics, and can be used as a photoresist with a resolution of sub micron level; It can also be used as an electronic packaging material by coating polyimide as a buffer layer on the surface of the chip, which can effectively prevent collapse caused by thermal stress; In addition, polyimide can also be used for flexible printed circuit boards.
Mechanical components: Polyimide can be used to produce various high-temperature resistant and high-strength mechanical parts. In China, polyimide is mainly used for heat exchange components, instruments, ship compressor piston rings, valve plates, etc. in automobiles. In addition, polyimide can also be used as high-temperature resistant, self-lubricating, sealing, and wear-resistant components for large motors, nuclear power plants, textile machinery, high-speed packaging equipment, gas compressors, and other applications.
Nano and liquid crystal fields: Polyimide also has a wide range of applications in the nano and liquid crystal fields. Fluorinated polyimides are transparent in the communication wavelength range and can be used as passive or active waveguide materials, optical switches, etc.
In the field of coatings, polyimide is one of its earliest applications in the preparation of coatings. This type of substance is mainly used as an insulation coating for enameled wires in coatings, especially as a high-temperature resistant coating or for electromagnetic wires, which can meet the insulation requirements in high-temperature environments.
Fiber material: High temperature resistant polyimide fiber is currently one of the hottest organic synthetic fibers in use, with characteristics such as high strength, high heat stability, and radiation resistance. It is a typical representative of the next generation of high-performance fibers. Polyimide dietary fiber, as a new variety in the global textile industry, integrates functions such as warmth retention, antibacterial, and native far-infrared. It can be used to produce functional products such as extreme cold warmth retention, antibacterial fabrics, and far-infrared health care.
Separation membrane: The ideal separation membrane material should have high air permeability and good air permeability selectivity, as well as high strength and chemical corrosion resistance. Polyimide possesses these characteristics and can be widely used in gas separation membranes for the separation of various gases such as hydrogen nitrogen, nitrogen oxygen, carbon dioxide nitrogen, or methane; Remove moisture from air, hydrocarbon feed gases, and alcohols; It can also be used as a pervaporation membrane and ultrafiltration membrane.
Other fields: Polyimide can also be used to make laser devices, copier separation claws, optical components, medical equipment, etc. It has excellent performance in many fields such as communication, environmental protection, biomedicine, etc.
In summary, polyimide materials rely on their excellent comprehensiveness
