3M™ Thermally Conductive Interface Pad Sheet 5591S


3M 5591S

Polyester film supported super soft, silicone elastomer with thermal conductivity of 1.0 W/mk. Conformable at low pressure to minimize stress on components and fill gaps.

Good dielectric properties. Handles easily without crumbling.


  • Good thermal stability of the base polymer with excellent softness of the thermal pad.
  • Good thermal conductivity in an ultra soft silicone polymer base.
  • The product tack is such that a mechanical means to support the pad in a final assembly is required.
