Most carry a UL rating of VTM-0. Polyimide laminates have a flexural strength half life at 249 C of 400 hours.

Typical polyimide parts are not affected by commonly used solvents and oils - including hydrocarbons, esters, ethers, alcohols and freons. They also resist weak acids but are not recommended for use in environments that contain alkalis or inorganic acids. Some polyimides, such as CP1 and CORIN XLS, are solvent-soluble and exhibit high optical clarity.
