Description

UniPhase 5500 is a non silicon, high performance, phase changing thermal interface material, formulated to function as a superb alternative to messy and inconsistent thermal grease. Supplied as custom cut parts or in
sheets, UniPhase 5500 will flow at a phase change temperature of 60°C and conform to the differing surface textures between a heatsink and LED COB or other device. In combination with device mounting pressure and
phase change flow, UniPhase 5500 expels air voids at the interface helping to reduce thermal resistance.

Benefits

  • Delivers a consistent and reliable thermal interface
  • Mounting pressures and phase change flow expels air between uneven surfaces reducing thermal impedance
  • Delivers a thin bond line between surfaces helping to improve thermal performance

Features

  • Silicon Free with Low thermal resistance
  • Highly reliable and consistent thermal interface for demanding applications such as LED COB
  • Non-reinforced film

Recommended Uses

  • Typically used to thermally connect an electrically isolated heat generating component to a heatsink
  • Within an application to replace thermal grease
  • Power supplies and power modules
