In the field of high-tech materials, polyimide PI has become an ideal material in various fields such as aerospace, electronic communication, and automotive industry due to its excellent heat resistance, mechanical strength, chemical stability, and electrical insulation performance. Polyimide PI comb teeth perform well in the following aspects:

1. High temperature stability: PI materials can maintain stable physical and chemical properties in high temperature environments, and their long-term use temperature can reach over 300 ° C. Some high-performance PI can maintain stability above 450 ° C in the short term, which makes PI comb teeth perform well in precision equipment that requires high temperature resistance.

2. Excellent mechanical properties: PI material has high strength, high modulus, and good toughness, which enables PI comb teeth to withstand large stress and deformation without being easily damaged, making it suitable for applications that require high accuracy and stability.

3. Low dielectric constant and loss: PI materials have low dielectric constant and dielectric loss, which is particularly important for high-frequency circuits and microwave devices. They can reduce energy loss during signal transmission and improve signal transmission efficiency.

4. Good chemical stability: PI materials have excellent corrosion resistance to most organic solvents and chemicals, and can maintain stable performance in harsh chemical environments, extending equipment service life.
