Vespel® Parts and Shapes are available from stock in five standard grades:

 

 

 

  • Vespel SP-1 - Unfilled. Maximum strength & elongation; lowest modulus & thermal conductivity: optimum electrical properties.
  • Vespel SP-21 - 15% graphite (by weight). Enhances inherent wear resistance, improves long term thermal stability.
  • Vespel SP-22 - 40% graphite (by weight). Gives low coefficient of thermal expansion. Maximum creep resistance.
  • Vespel SP-211 - 15% graphite and 10% TEFLON® fluorocarbon resin (by weight). Lowest static friction.
  • Vespel SP-3 - 15% MoS2(by weight). Best wear performance in dry environments.
  • Vespel SP-202 - For electrical conductivity with lower wear rates. Maintains tolerances in high heat and through multiple cycles. Removes electrostatic charge.
  • Vespel SCP-5000 - Unfilled. High strength, hardness, chemically resistance over broad temperature range. Offers high wear resistance with low outgassing and high purity. Very good thermal oxidative stability.
  • Vespel SCP-5009 - For high temperature resistance and better compressive strength. Lower CofF without lubrication. Excellent sealing capability.
  • Vespel SCP-50094 - For high temperatures and wear resistance. This grade offers superior wear resistance and thermal oxidative stability.
  • Vespel SCP-5050 - For high temperatures, wear resistance and exceptional CofF. Coefficient of thermal expansion similar to steel. Improved high temperature performance.
