An emerging need for thermal management
Today’s high intensity LEDs are opening up new opportunities for cost savings and reduced
power consumption; however, they also generate more heat than conventional LEDs. Its
important to remember that the higher the temperature at which LEDs operate, the less
efficient they become making improved thermal management essential for optimal
performance. That’s where 3M can help.
3M Thermal Interface Materials provide efficient thermal transfer for long-term reliability and
performance optimization in applications using high brightness LEDs. 3M Thermal Interface
Materials have a proven track record of durability and high thermal performance in a variety
of environmental conditions to meet the demanding needs of applications today and in the
future. 3M provides a full selection of products to meet customers' process and performance
requirements, including thermally conductive pads, adhesives, and greases.
Advanced designs drive need for

Durability of interface: Especially in external
applications of LEDs, durability of the thermal
interface is important to support efficiency in
different environmental conditions. 3M products
have shown excellent durability through

Note: For applications using a thermal pad, the 3M Acrylic Thermal pads are slightly tacky on one side for generally acceptable
assembly adhesion in many applications. If higher adhesion is desired, 3M suggests the testing of the 3M Acrylic
Adhesive Transfer Tape 9461.
The tack adhesion strength of the 3M Thermal Pads is sufficient for holding the product in place for assembly and use,
etc. in many applications. The end use design of the LED Structure/Thermal Pad/Heat Sink does require an added
mechanical means of assembly to ensure long term mechanical integrity and thermal performance.
3M also offers a line of silicone based thermal pads ranging in thermal conductivity from 1.0 W/m-K to 4.9 W/m-K.
Please contact 3M for additional product information and inquire about 3M Thermally Conductive Interface Pads
5591(S),5592(S),5595(S),5516(S) and 5519(S).
