  • 3M™ 5516 Thermally Conductive Silicone Interface Pad


  • Available in 20 to 80 mil thickness (1.0 mm to 2.0 mm)
  • Good thermal conductivity and good electrical insulation properties.
  • Good softness and conformability even to non-flat surfaces.
  • Softness results in low stress on board components.
  • “S” version incorporates a thin polymeric film carrier for improved handling and a non-tacky surface for ease of rework.
  • Slight tack allows pre-assembly. Good wettability for better thermal conductivity
