Silicone thermal release sheet

In recent years, heat dissipation measures that accompany the miniaturization and high performance of electrical and electronic equipment have become important.
“Thermo-release” is a highly flexible silicone sheet with excellent thermal conductivity. It is a high-performance material that efficiently drives heat in between a heat source such as CPU, Power IC, LED, etc. and a heat sink / metal frame.


  • ◇Thermal insulation material for LED lighting and backlight
  • ◇Heat dissipation insulation for battery module
  • ◇Heat dissipation insulation for automotive power devices
  • ◇Heat dissipation insulation for power transistors for power supplies
  • ◇Heat dissipation insulation for such as CPU and MPU


  • ◇Extremely flexible, so it adheres closely to the heating element and cooling parts and exhibits a high heat dissipation effect.
  • ◇Excellent electrical insulation and flame resistance.
  • ◇Easy to attach / detach to the heating element and excellent workability.
  • ◇Can be used in a wide temperature range.
  • ◇Provide high cost performance by reasonable manufacturing methods and material procurement.

We have a wide track record in heat countermeasures for LED lighting, IC boards, etc.
We have products such as double-sided adhesive, single-sided non-adhesive, and with substrates for different applications.
