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
    GX30000DS series
  • Features
    • Thermal conductivity:3.5 W/m·K, Hardness:40(Shore OO)
    • Highly flexible with excellent thermal conductivity that swiftly conducts heat to heat sinks.
    • Excellent workability and reworkability due to its three-layer structure of a low-tuck layer, the main thermal conductive layer and non-tuck layer.
    • It has a tack-free layer suitable for contact with uneven surfaces that are prone to oil bleeding.
    • 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.
