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.

Grades

● Duratron™ D7000 PI
● Duratron™ D7015G PI
● Duratron™ D7040G PI

  • Extremely high max. allowable service temperature in air [240 °C continuously, with short term excursions up to 450 °C]
  • Excellent retention of mechanical strength, stiffness and creep resistance over a wide range of temperatures
  • Good sliding properties and excellent wear resistance
  • Very good dimensional stability
  • Inherent low flammability
  • Good electrical insulating and dielectric properties [only applies to Duratron™ D7000 PI]
  • Low outgassing in vacuum [dry material]
  • High purity in terms of ionic contamination [Duratron™ D7000 PI]
  • Excellent resistance against high energy radiation
  • Polyimide parts should be stored in dry, clean, and sealed packaging to minimize dimensional changes caused by moisture absorption.
  • Machined parts that will operate at high temperatures or require tight tolerances should be dried before use and kept dry throughout operation.
  • Valve and pump seats
  • Seals and wear surfaces
  • Structural and wear parts for semiconductor and electronics manufacturing
  • Fixtures and handling parts for glass and plastics manufacturing
  • Metal replacement for aerospace components
