Polyimide Film Properties


Thermosetting polyimide has excellent thermal stability, chemical corrosion resistance and mechanical properties, usually orange color. The flexural strength of the graphite or glass fiber-reinforced polyimide can reach 345 MPa, and the flexural modulus is 20GPa. The thermosetting polyimide is very small in creep and has high tensile strength. Polyimide uses a wide range of temperature, from minus 100 to two hundred or three hundred degrees.


Polyimide property is stable. Polyimide does not need to add a flame retardant to prevent combustion. The general polyimide is resistant to chemical solvents such as hydrocarbons, esters, ethers, alcohols and halothane. They are also resistant to weak acids but are not recommended for use in strong alkali and inorganic acid environments. Some polyimide such as CP1 and Corin xls are soluble in solvents, and this property helps to develop their applications in spraying and cryogenic cross-linking.
