HEATEX™ High Thermal Conductive Sheet

Insulation-type high thermal conductive sheet which withstand bending and cracking

HEATEX™ has vertically oriented fillers with high thermal conductivity. Boron nitride with high thermal conductivity is used for making of the fillers.
HEATEX™ can be used as an interface material (TIM) to transfer heat efficiently from heat-generating parts such as CPU, LED backlight, and power chips to cooling parts such as heat sink.

HEATEX™ High Thermal Conductive Sheet

Features

1. Various specifications of insulation.
2. High thermal conductivity, one of the highest on the market.
3. A rubber type soft sheet TIM without being over adhesive.*

Handling

Highly thermally conductive heat-dissipating sheet that is resistant to cracking even when bent

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

Thermal Stability

Maintains low thermal resistance in pressurized environments.
Even if it is used for a long time in an environment of 200°C, there is almost no change in physical properties.
In addition, the pump-out phenomenon caused by thermal paste is less likely to occur.

*Pump-out phenomenon
As materials expand and contract repeatedly due to the rise and fall of the temperature, the grease which was in contact with the materials will be pushed out, thus creating the pump-out phenomenon.
When the pump-out phenomenon occurs, the contact thermal resistance increases due to the formation of gaps, hence the initial efficiency cannot be attained.
