DESCRIPTION
General description
Pyromellitic dianhydride (PMDA) is an acidic anhydride that can be used as a repair agent and as a chain extender in the formation of polyethylene terephthalate (PET) based chain extensions. It is mainly used in the production of thermoplastics and other coating applications.
Application
PMDA can be used to synthesize aromatic polyimides with excellent thermo-mechanical and chemical properties. It may also be used as a capping agent in the development of siloxane based hybrid materials for potential usage in organic electronics.
