DuPont™ Vespel® SP-202

Conductive polymer offers electrostatic charge removal for high temperature substrate handling applications

DuPont™ Vespel® SP-202 is ideal for high temperature substrate handling applications such as contactor pads, rollers, guides, and lift pin components. It offers electrostatic charge removal, high temperature resistance, low wear rates, and machines easily to tight tolerances.

Challenges for high temperature handling applications 

  • Preventing tribological static charges from damaging electronic components during manufacture and handling.
  • High-end conductive plastics are too brittle, extremely expensive to fabricate, and degrade quickly from heat aging.
  • Other advanced engineering plastics do not have the thermal properties to take the heat.
  • Positioning tolerances are critical. High wear rates lead to contamination and poor positioning.
  • Metals and ceramics are too hard and abrasive and they can damage the components being handled.

Solution - DuPont™ Vespel® SP-202 handling components

  • Electrostatic charge removal. Vespel® SP-202 is a conductive plastic grade with surface and volume resistivity values in the range of 10–1 to 101 (ohm, ohm-cm).
  • Vespel® SP-202 has the thermal resistance to maintain tolerances in high heat applications and through multiple thermal cycles.
  • Lower wear rates on contact surfaces generate longer part life and cleaner environments.
  • Vespel® SP-202 can be machined to tight tolerances with relative ease.

Benefits of using DuPont™ Vespel® SP-202

  • Although material cost is higher than some engineering plastics, lower scrap rates and machining cost may yield offsetting savings during the fabrication process.
  • Low wear rates will provide consistent positioning and long part life resulting in high production utility and low maintenance cost.
  • Low particle generation will keep operating environments clean.
  • Properly grounded components will not hold a charge preventing the attraction of dust and other charged particles.
