3M Thermal Conductive Silicone Pads

Thermally conductive silicone interface pads provide extraordinary thermal conductivity as well as dielectric strength. These soft, thermally-conductive silicone interface pads are used to transfer heat from a hot surface to a cooler region of the assembled design. This type of positive heat transfer alleviates most concerns relating to the overheating of an electronic device due to concentrated heat buildup. Moreover, heat conductive silicone pads allow for the seamless transfer of heat from its production source to cooler areas where the heat can dissipate.
3M Thermally Conductive Silicone Interface Pads are available in a variety of thermal conductivities and softness grades to provide excellent gap filling, low assembled stress and a high degree of wet-out for more efficient heat transfer.  3M Thermally Conductive Silicone Interface Pads are easily die cut to most shapes, and have a tacky conformable performance on both sides. These pads are perfect for uses in automotive batteries, industrial applications, and high temperature solutions..

Advanced Benefits of 3M Thermal Conductive Pads

Silicone interface pads provide an effective and suitable way to transfer heat between active thermal components and heat sinks. Some of the advantages associated with utilizing heat conductive silicone pads, include:
  • UL-94 V-O certified
  • Soft and conformable
  • High temperature tolerance
  • High thermal conductivity
  • Light tack allows for pre-assembly
  • Outstanding compressive stress relaxation over electronic device
  • High temperature resistance
  • Good wettability for improved and lower thermal resistance
  • Good dielectric properties

Differentiating Between Acrylic & Silicone Interface Pads

Thermal conductive pads provide an excellent way to transfer heat from hot surfaces within a device to areas that maintain a cooler operating temperature.
Acrylic thermal management materials are a preferred solution for electronic applications.  Acrylic TIM’s by 3M do not contain silicone oils which bleed throughout the electronic components which can cause many problems including corrosion of electrical connections.  Acrylic thermal material from 3M is low outgassing, unlike silicone pads, and provides excellent dielectric qualities as well.
Acrylic thermal solutions from 3M provide outstanding conformability and gap filling properties that allow for easy and controlled heat flow from one area of the device to another. Acrylic thermally conductive material also provide advanced environmental durability and can provide operative heat transfer performance up to 130° C.  Acrylic pads offer a lower cost option, when compared to the equivalent silicone thermal pad..

Conversely, silicone interface pads can provide excellent heat durability with the ability to withstand temperatures up to 200C.  However, in an electronic application that temperature range is generally unnecessary.  Silicone thermal pads are an excellent option for industrial, rugged high temperature solutions.  And when heat is applied, silicone thermal pads can be extremely soft for conformability challenges. 


Heat Conducted Silicone Thermal Pad Application Process

Before installing a silicone interface pad, the installation area should be clean and dry to ensure the best possible thermal performance. For the cleanest possible surface isopropyl alcohol (isopropanol) should be applied with a lint-free wipe or swab, which will remove any surface contamination such as dust or fingerprints. Furthermore, the silicone thermal pads should be installed in temperatures ranging from 0° to 40° C for improved adhesion.
