Polyimide [PI]

PI delivers a unique combination of properties, excelling in applications that demand low wear and long life in harsh environments. Ideal for situations where thermal requirements exclude Duratron® PAI but don’t require the exceptional heat resistance of PBI, PI is trusted for critical components in the automotive, aerospace, defense, electrical, glass, nuclear, and semiconductor industries.
