Why is polyimide tape called "golden tape"?

1) Brief introduction of PI film

PI film is currently the best film insulating material in the world, with excellent mechanical properties, electrical properties, chemical stability, high radiation resistance, high temperature resistance and low temperature resistance (-269°C to +400°C)

2) PI film is distinguished according to the production process:

1 dipping method

Less investment, but high production cost and limited product performance

2 cast film

Low production cost, uniform film, good product quality

3 biaxially stretched film

The investment is large, but the physical, electrical and thermal properties of the product are excellent

3) PI film products

4) PI film application

Film was one of the earliest commercial products of polyimide, mainly used for Class H or Class C insulation. Because polyimide tape has excellent comprehensive properties such as high oil resistance, heat resistance and low dielectric loss, it has the reputation of "golden tape". It can be used as cable insulation material, heat insulation material, radiation protection protection material, recording carrier material, etc., especially in the application of flexible printed circuit board industry, making it widely used in aerospace, military, mobile communications, laptop computers, computer peripherals, PDA digital cameras, electrical instruments and other fields have been widely used and become irreplaceable key materials in the electric power, electrical appliances, microelectronics and precision machinery industries.

PI films are widely used in the field of microelectronics, as well as OLED white light lighting, thin film solar cells, transparent films for preventing electromagnetic radiation, radio frequency circuit boards, touch screens and other fields (OLED displays)
