Thermal conductive sheet

Thermal conductive sheet Silicone Type

Silicone type featuring high thermal conductivity and flexibility that rapidly conveys heat to heat sinks.

  • Product name
    EX40000DS series
  • Features
    • Thermal conductivity:1 W/m·K, Hardness:12(Shore OO)
    • It has the highest flexibility among our thermal conductive sheets. Since it follows uneven surfaces with low stress, it eliminates gaps in a heat dissipation structure to make the load uniform over the surface.
    • Single tack free layer realizes high workability and flexibility.
    • Features low molecular-weight siloxane gas volatility, minimizing the risk of contact fault to components such as substrates even over prolonged periods of usage.
    • Halogen-free with high levels of flame resistance.
