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.

Applications & Cases

Introducing our product applications and cases for various industries.

Bonding material usable at high temperatures where solder cannot be used

This is a bonding material in the form of a paste containing silver nanoparticles. After heating, the paste becomes a sintered body, but it exhibits the same performance (heat resistance, electrical conductivity, thermal conductivity, etc.) as bulk silver and achieves high shear strength.

Thermal conductive sheet to dissipate heat generated by heat-generating parts

Vertical orientation of the thermally conductive filler increases the heat transfer path, resulting in a high thermal conductivity.
