PI polyimide has excellent comprehensive properties, which can meet the requirements of low wear and long service life in harsh environments.The value of PI is also reflected in the application fields where the thermal performance of PAI cannot meet the requirements and the ultra-high thermal performance of PBI does not work.Therefore, PI products are mainly used in automotive, aerospace, national defense, electronic and electrical, glass, nuclear industry and semiconductor industry and other demanding applications.
Main performance:
1. Maximum working temperature in atmospheric environment (240℃ continuous use, short-term exposure to high temperature environment up to 450℃)
2. It has mechanical strength, rigidity and creep resistance under a wide range of temperature conditions
3. Good sliding performance and excellent wear resistance
4. Excellent dimensional stability
5. Inherent low combustion performance
6. Good electrical insulation and dielectric properties
7. Low vacuum permeability (dry material)
8. It can maintain high purity in ion polluted environment
9. Excellent resistance to high-energy radiation
