 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 Pyromellitic Dianhydride (PMDA)  CAS NO.89-32-7


  1. Excellent thermal stability
  2. Good chemical resistance
  3. Stable mechanical properties
  4. Polyimide does not require the addition of flame retardants to prevent combustion.
