Thermal Gap Pads

Thermal Gap Pads

Long-term, reliable protection of sensitive circuits and components is important in today’s delicate and demanding power electronics applications. With the increase in processing power, charging wattages and the trend toward smaller, more compact electronic modules, transfer of thermal energy to heat sinks, cooled chassis and other safe locations is essential in maintaining component temperatures within operating specification limits. Resin Designs’ family of thermal interface pads provide superior performance with a variety of thermal pad constructions to achieve excellent thermal protection and economic value over a wide range of applications.

Quick Links


  • Thin thermal pads and gap filler thermal pad materials are cold applied
  • Require no heating or curing
  • Materials can be removed easily and cleanly
  • No special tools required for access and rework.

Features & Benefits:

  • These thermally conductive silicones function as heat transfer media, barriers against:
    • Environmental contaminants
    • Stress relieving shock
    • Vibration absorbers over a wide temperature and humidity range.
    • High-compressibility accommodates tolerance stack up
    • Requires a lower clamping force, reducing system costs.
