Thermal Interface Materials

The following table shows a sampling of what's available in thermal interface
materials (TIMs) and includes greases, epoxies, and pads. It is sorted by
thermal conductivity, but this is not the only parameter of concern. When
selecting a TIM consider:

• Electrical conductivity (Some TIMs conduct electricity as well as heat.)
• Operating temperature range
• Expansion coefficient
• Pressure (Mounting pressure can make a significant difference in performance.)
• Outgassing (A concern within sealed packages or in space applications.)
• Bleeding (silicone-based greases can bleed.)
  
• Surface finish (Some TIMs fill large gaps in irregular surfaces better than others.)
• Ease of installation
• Cost
