KERATHERM® Phase Change Material (PCM)

Optimum adaptation to the smallest irregularities

Kerafol's PCM films are a combination of melt waxes with or without support material.
The wax-based material with melting properties levels even the tiniest bumps between the power module and the heat sink, improving surface contact and increasing heat transfer.

As soon as the melting temperature is reached, the material softens to fill even the smallest bumps between the power module and the heat sink.


Applications

  • IGBT
  • CPU

Advantages

  • leveling the smallest bumps between power module and heat sink by melting the material
