Polyimide Film Technology

Polyimide has been widely used in electrical appliances, electronic devices, aerospace, new energy and other fields due to its excellent comprehensive properties such as high temperature resistance, high strength, high modulus, electrical insulation, radiation resistance, corrosion resistance, and humidity resistance. Applications. With the development of modern technology and industry, the application field of polyimide film is expanding, and the global demand for polyimide film is increasing day by day. At present, the application of polyimide film in the fields of electrical insulation, electronic devices, flexible display, and 5G communication is gradually developing towards subdivision, diversification, and customization. There is an urgent need for high insulation, low expansion, high transparency, low/high Dielectric, high thermal conductivity polyimide film and other varieties. After decades of development, my country has achieved certain research results in the field of polyimide films, but its technical capabilities are still relatively backward, and technological breakthroughs have yet to be achieved in high-end fields such as high-speed variable frequency motors, flexible copper clad laminates, and new displays. .

In order to promote the interaction of polyimide film research and development, production, application and other links, and promote the technological breakthrough and industrial upgrading of polyimide film, Chifei has been continuously cultivating in this field and found that ultrasonic spraying can be well used for insulating materials. .
