Thermal conductive sheet

Thermal conductive sheet Acrylic Type

Acrylic type non-silicone thermal conductive sheet that features high thermal conductivity and flexibility.

  • Product name
    UX3004D series
  • Features
    • Thermal conductivity:3 W/m·K, Hardness:85(Shore OO)
    • Thin with excellent workability, while being durable and retaining flexibility for long periods.
    • No production of low-molecular-weight siloxane gas that causes contact damage on parts such as substrates.
    • Since it has a tack-free layer of low ductility in the top layer, it excels in workability and reworking nature.
    • Halogen-free with high levels of flame resistance.
