Hi-Flow 105

Hi-Flow 105 is a phase change material coated on both sides of an aluminum substrate. It is designed specifically to replace grease as a thermal interface, eliminating the mess, contamination and difficult handling associated with grease. Hi-Flow 105 is tack-free and scratch resistant at room temperature and does not require a protective liner in shipment when attached to a heat sink.

At 65°C (phase change temperature), Hi-Flow 105 changes from a solid and flows, thereby assuring total wet-out of the interface. The thixotropic characteristics of Hi-Flow 105 reduce the pump-out from the interface.

Hi-Flow 105 has thermal performance equal to grease with 0.10 °C-in²/W contact thermal resistance.

Your Benefits

  • Thermal impedance 0.37°C-in²/W (@25 psi)
  • Used where electrical isolation is not required
  • Low volatility – less than 1%
  • Easy to handle in the manufacturing environment
  • Flows but doesn’t run like grease


  • Power semiconductors
  • Microprocessors mounted on a heat sink
  • Power conversion modules
  • Spring or clip mount applications where thermal grease is used
