Thermally Conductive Pads

THERM-A-GAP® gap filler pads and CHO-THERM® Electrical Insulator Pads from Chomerics

Parker Chomerics THERM-A-GAP™ gap filler pads are a family of low soft, thermally conductive silicone and non-silicone elastomers for applications where heat must be conducted over a large and variant gap between a semiconductor component and a heat-dissipating surface. Typical applications include:

  • Telecommunications equipment
  • Consumer electronics
  • LEDs, Lighting
  • Handheld devices
  • Vibration dampening


Features & Benefits:

  • Ultra low deflection force
  • Range of thermal performances available
  • High tack surface reduces contact resistance
  • Various thicknesses available, finished in standard sheets
  • Custom sized configurations and/or cut parts are available as individual parts, or on sheets
