3M™ Thermal Conductive Silicone Pads
Thermally conductive silicone interface pads provide exceptional thermal conductivity and dielectric strength. These soft silicone interface pads transfer heat from a hot surface to a cooler region of the assembled design. This positive heat transfer reduces the risk of overheating from concentrated heat buildup. Heat-conductive silicone pads allow for the seamless transfer of heat from its production source to cooler areas where the heat can safely dissipate.
3M Thermally Conductive Silicone Interface Pads are available in various 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. These silicone pads can be die-cut to most shapes and have a tacky, conformable performance on both sides. These pads are ideal for rugged, high-temperature applications, including:

- Light tack allows for pre-assembly
- High-temperature resistance
- Good wettability for improved & 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
Acrylic thermal management materials are a preferred solution for electronic applications. Acrylic pads do not contain silicone oils, which can bleed throughout the electronic components. This causes problems, including corrosion of electrical connections. Unlike silicone pads, acrylic thermal material from 3M is low outgassing and provides excellent dielectric qualities.Acrylic thermal solutions from 3M also provide exceptional conformability and gap-filling properties, allowing for easy and controlled heat flow from one area of the device to another. Acrylic thermally conductive material also provides advanced environmental durability. Acrylic pads offer a lower cost option when compared to the equivalent silicone thermal pad.
