3M™ Thermally Conductive Silicone Interface Pad 5590H is a highly conformable, slightly tacky silicone elastomer pad. Designed to provide heat transfer path between heat generating components and heat sinks, heat spreaders or other cooling devices.


  • Good thermal conductivity (3.1 w/m-k)
  • Good softness and is conformable at low pressure ( Shore 00 = 50)
  • Softness results in low stress on board components
  • Good dielectric properties
  • Slight tack allows pre-assembly. Good wettability for better thermal conductivity
  • UL 94 V-0
  • High temperature résistance
  • Tacky both sides
  • Thickness : 0.5 mm,1.0 mm, 1.5 mm, 2.0 mm, custom thickness
  • Larger sheet size is available


3M 5590H05 Thermal Silicone Interface Sheet

SKU: TH001
    • Can be slit to custom sizes
    • Paper or Plastic core available.
