Introduction of the Polyimide
Polyimide (sometimes abbreviated PI) is a polymer of imide monomers. Polyimides have been in mass production since 1955. With their high heat-resistance, polyimides enjoy diverse applications in roles demanding rugged organic materials, e.g. high temperature fuel cells, displays, and various military roles. A classic polyimide is Kapton, which is produced by condensation of pyromellitic dianhydride and 4,4′-oxydianiline
Feature of CAS NO.2540-99-0 DSDA
- Excellent thermal stability
- Good chemical resistance
- Stable mechanical properties
- Polyimide does not require the addition of flame retardants to prevent combustion.
