Thermal Interface Materials

3M™ thermal interface tapes, pads, and epoxies provide high thermal conductivity

Thermal Interface Materials3M thermal interface tapes, pads, and epoxies provide high thermal conductivity by focusing on the two areas that matter most: bulk conductivity and interface conductivity. They address a crucial problem with today's low-power electronic devices – the need to dissipate the sizable amounts of heat being generated.

The thermally conductive adhesive transfer tapes provide efficient thermal transfer for a wide range of applications including bonding heat sinks, heat spreaders, IC packages, power transistors, and more. These tapes combine 3M high-performance acrylic adhesive with highly conductive ceramic particles for an extremely reliable and user-friendly thermal interface. They also offer a highly conformable construction that provides excellent wet-out on surfaces.

The thermally conductive interface pads provide high levels of conductivity for the most demanding electronics applications. They also provide excellent handling and can be die-cut to fit most applications.

The thermally conductive epoxies have a range of liquid adhesives with minimal odor and superior structural strength adhesion. The adhesive flows and fills micro-spaces on surfaces and the ultra-thin bond line helps achieve low thermal impedance.

5591/5591S
3M™ Thermally Conductive Interface Pads 5591 and 5591S are designed to provide a preferential heat-transfer path between heat-generating components and heat sinks, heat spreaders, or other cooling devices.
  • The specialized silicone chemistry of interface pads 5591/5591S provides for good thermal stability of the base polymer with excellent softness of the thermal pad.
  • Interface pads 5591/5591S offer good thermal conductivity in an ultra-soft silicone polymer base.
  • Interface pads 5591/5591S have a permanent polyester film 12 μm thick on one side to provide for a non-tacky surface, increased puncture resistance, ease of handling and rework.
  • Interface pads 5591/5591S have a tacky feel. The product tack is such that a mechanical means to support the pad in a final assembly is required.
