Overview DuPont™ Vespel ® polyimide is an extremely high temperature, creep resistant material that is often used in high heat environments where thermoplastic materials would lose their mechanical properties.

Vespel ® is available in a variety of formulations including an unfilled grade and several bearing and wear grades.

    Vespel ® SP-1

    Unfilled Vespel ® SP-1 has outstanding sealing properties when it interfaces with metal mating parts. These properties make Vespel ® ideal for use in un-lubricated, high temperature, and high pressure or high vacuum valve seat and gasket applications.

    Bearing Grades of Vespel ®

    Vespel ® SP-21, SP-22, SP-211, and SP-3
    Bearing grades of Vespel ® will operate successfully without lubrication in high load, high speed, and/or high temperature environments where thermoplastic bearings and many metal bearing materials will quickly fail.

    Introducing...

    Vespel ® SCP-5000

    Technology advances have led to the development of DuPont™ Vespel® SCP-5000, an unfilled polyimide copolymer developed for demanding applications that require toughness, thermal and dimensional stability, chemical resistance and stable dielectric performance across a broad temperature range.

    This product is a good candidate for applications such as CMP retaining rings, test sockets, substrate lift pins or any other application that requires high temperature and/or high wear resistance with low outgassing.

    Compared to Vespel ® SP-1, SCP-5000 offers:

    • Higher modulus, strength, and surface hardness
    • Improved dimensional stability

Vespel ® Standard Sizes

SHEET 10"x10" (0.062"-2.0" thick)
ROD diameter 0.25"-6.0"
  • Length, width, thickness, and diameter tolerances vary by size and by manufacturer
  • Custom sizes and colors available upon request
  • Many of our plastic materials are available as films with thicknesses of 0.029" or less

Vespel ® Grades

  • Unfilled
  • Bearing

NOTE: Several grades of Vespel ® are available. For additional information on Vespel ® polyimide shapes, contact your local Curbell Plastics representative or call Curbell at 1-888-287-2355.
