Silicone Putty

SARCON® Silicone Putty is a highly conformable, thermally conductive, non-flammable interface materials. It’s thermal performance is equal to our most highly rated GR-m and XR-e Silicone Gap Filler Pads.

Three formulations are available, GR-Pm and XR-Pe. The surface consistency is excellent for filling small air gaps and uneven mating surfaces, making reliable contact with various shapes and sizes of components.


  • Very low compression force at high compression rate
  • Suitable for gaps as small as 0.3mm or less
  • UL94 V-0 certified
  • Available in three formulations

Available Configurations:

  • Sheets
  • Die-cuts

Applications:

  • Between chassis wall and heat sink
  • Between CPU and heat sink
  • Between semiconductor and heat sink
  • Component to heat spreader
