Vespel® SP By DuPont

Vespel® SP polyimide shapes (Vespel Sheet and Vespel Rods) are produced from advanced polymers developed by DuPont. We offer all Vespel grades in both basic shapes and finished parts.

Dupont Vespel® polyimide is available in five standard grades:
  • Vespel® SP-1 - Unfilled. Maximum strength & elongation: lowest modulus & thermal conductivity: optimum electrical. Vespel® SP-1 is available in Rods, Bars, Plates & Parts.
  • Vespel® SP-21 - 15% graphite (by weight). Enhances inherent wear resistance, improves long term thermal stability. Vespel® SP-21 is available in Rods, Bars, Plates & Parts.
  • Vespel® SP-22 - 40% graphite (by weight). Gives low coefficient of thermal expansion. Maximum creep resistance. Vespel® SP-22 is available in Rods, Bars, Plates & Parts.
  • Vespel® SP-211 - 15% graphite and 10% TEFLON® fluorocarbon resin (by weight). Lowest static friction. Vespel® SP-211 is available in Rods, Bars, Plates & Parts.
  • Vespel® SP-3 - 15% MoS2 (by weight). Best wear performance in dry environments. Vespel® SP-3 is available in Rods, Bars, Plates & Parts.
