High thermal conductivity sheet HEATEX™


  • HEATEX™ has an extremely high thermal conductivity in the thickness direction and contributes to the low thermal resistance of various electronic devices.
  • Two types are available: Insulation type and Conductive type.
  • HEATEX™ has a wide range of thickness lineup and high thermal conductivity.

Click for lineup

HEATEX™ has vertically oriented thermally conductive fillers with high thermal conductivity. 
It can be used as an interface to efficiently transfer the heat from heat-generating parts (CPU, LED backlight, power chip) to cooling parts (heat sink, so on..)

Stable and easy to handle

Easy to handle

It is hard to break even when bent, has a silky feel, and has excellent workability.
Rework is also possible.
Adhesive treatment of the sheet surface is available as an option.


Maintains low thermal resistance in pressurized environments.
Even if it is used for a long time in a harsh environment of 200°C, there is almost no change in physical properties.
In addition, not as thermal grease, no pump-out phenomenon occurs.

* Pump out phenomenon

Materials that come into contact with grease undergo a pump-out phenomenon in which grease is discharged by repeating expansion and contraction as the temperature rises and falls.
When the pump-out phenomenon occurs, the contact thermal resistance increases due to the generation of voids, and the initial performance cannot be obtained.
