Gap Pads

Thermally conductive gap pads offer, besides excellent thermal properties, the ability to even out small, medium and big gaps and tolerances between the component (hot spot) and the cooling device.

Gap pads are based on silicone and are filled with ceramic particles. They are tacky by nature. This can be single- or double sided. The use of an adhesive tape is not necessary in most cases.

  • Excellent conformability
  • Easy installation and handling
  • Very good thermal properties
  • Naturally both side tacky as standard, other options available
  • Adhesive tape on request
  • Also available in a silicon-free version
  • Insulating up to insulation group I: CTI 600

More details about gap pads.

The tolerances for our gap pads can be found here.

  • RoHS compliant
  • REACH compliant
  • UL 94-V0 certified product
