3M Thermally Conductive Interface Materials

3M™ Thermally Conductive Interface Materials

3M thermal interface materials efficiently and effectively conduct heat from your hot source to your cooling devices, be it heat sink, fan, heat pipes, or metal frames. 3M thermal solutions offer long-term stability at high temperatures and are ideal for applications such as managing heat from hot spots on LED lighting, backlights, lithium ion batteries, PC boards, or power IC chips.

• Thermally Conductive Adhesive Transfer Tapes
  Designed for quick heat transfer as well as mechanical bonding for all electronics, power supplies, circuit boards, and LED lighting.
• Thermally Conductive Interface Pads (Gap Pads)
  Provide effective and quick heat transfer and vibration dampening for LED lighting and consumer electronic devices. Excellent wet-out during assembly.
• Thermally Conductive Epoxy
  Provide a permanent ultra-thin bond line and even flow to fill small surface gaps, ensuring maximum heat flow at all points.
• Thermally Conductive Greases
  A high-performance cost-effective heat transfer method that can be used with many electronics applications.

3M™ Thermally Conductive Adhesive Transfer Tapes (custom sizes and die cutting available)
Designed for quick transfer of heat to heat sinks or other cooling components, in all electronics, power supplies, circuit boards, and LED lighting. No setup time compared to epoxies and greases—just stick and go. Can be used to secure heat sinks and spreaders. Available in a variety of thicknesses and easily die-cut to fit your requirements.

3M thermal tapes:

• have pressure sensitive double sided adhesive with thermally conductive fillers
• improve efficiency and longevity of straight or curved LED light fixtures
• replace or reinforce mechanical fastener systems
• are removable, enabling repairs
• provide differentiated adhesives for bonding different types of surfaces
• conform to a variety of surfaces

3M™ Thermally Conductive Interface Pads / Gap Pads
(custom sizes and die cutting available)
3M thermal pads provide effective and quick heat transfer and vibration dampening for LED lighting and consumer electronic devices. Excellent wet-out during assembly. With a light tack, the pads can be laid out for pre-positioning or used in multi-layer lamination.

3M thermal pads:

• provide ideal solutions for power COB LEDs, automotive Li+ batteries, notebook thermal modules, and more
• disperse heat in high wattage applications
• can be die cut to fit most applications
• can replace graphite for general purpose applications
• fill gaps between irregular surfaces
• are soft, compressible and conformable

Available in Silicone and Acrylic (non-silicone) versions

3M™ Thermally Conductive Epoxy
3M thermally conductive epoxy is a liquid adhesive that has good thermal conductivity with high structural strength, excellent wetting and minimal odor. Dispensing is easy for high output, in-line automatic manufacturing or manual application.

3M thermally conductive epoxies:

• fill small surface gaps and micro spaces
• provide ultra-thin bond lines and even flow
• have a low viscosity, ideal for low thermal impedance
• are mechanically much stronger than tapes and pads
• have low chloride ion contents and low outgassing

3M™ Thermally Conductive Greases
3M thermally conductive grease is a high-performance thermal interface material for transferring heat from the hot source to heat sink or other cooling devices. Thermal greases, as low cost and reliable materials, can be part of a multi-step heat transfer system to meet your requirements.

3M thermally conductive greases:

• can be removed, reshaped, and reused
• can be applied in screen printing (lower viscosity version)
• provide bulk conductivity
• provide thin bond line with low thermal impedance
• do not contain silicone
• can be used with other thermal materials
