Aerospace, DuPont™ Vespel®


The aerospace and space industries are rapidly advancing and new engineering challenges demand materials that can withstand the extreme temperatures, high stress, and harsh environmental conditions aircrafts and spacecrafts are exposed to. DuPont™ Vespel®, a high-performance polyimide, stands out as a material that meets these rigorous requirements.

Properties of Vespel®

Known for its many properties that set it apart from metals and other engineered plastics, including thermal stability, high mechanical strength, low friction and wear, chemical resistance, dimensional stability, and lighter weight than metals, Vespel® has become a critical component in the aerospace industry. As a result of its incredible versatility, it is commonly used for thermal insulation components, bearing and wear components, valve seats and seals, electrical insulation, and structural components, making it a highly desirable and valuable material.


There are 5 different forms of DuPont™ Vespel® SP Round Rods, each with unique features that make them best suited for specific tasks.

  • DuPont™ Vespel® SP-1 is best known for its superior wear and insulation properties.
  • DuPont™ Vespel® SP-21 is a graphite-enhanced material with low-friction properties.
  • DuPont™ Vespel® SP-22 boasts minimal thermal expansion.
  • DuPont™ Vespel® SP-211 provides a lower coefficient of friction than the SP-21 without lubrication in various applications.
  • DuPont™ Vespel® SP-3 is equipped for use in vacuum or dry environments.


There are also 4 different forms of DuPont™ Vespel® SCP Round Rods.

  • DuPont™ Vespel® SCP-5000 is ideal for demanding applications that require tough material.
  • DuPont™ Vespel® SCP-5009 is best suited for high wear and friction applications.
  • DuPont™ Vespel® SCP-5050 is known for its high temperature performance and wear resistance.
  • DuPont™ Vespel® SCP-50094 is used for applications that require high temperature and wear resistance.
