Polyimides (PIs) occupy a particular place in commercial plastics because of their ability to tolerate and function in extremely high temperatures. They are also well known for other beneficial properties including insulating capability, chemical resistance, and excellent mechanical attributes. With their combination of properties and their ability to be tailored toward application specifics, polyimides offer some of best options for performance in high heat and other difficult environments. This white paper provides a brief overview of polymide properties, their structure, and how they are synthesized for use in extreme environment applications.
