3M Non-Silicone
Thermal Interface Pads

Non-silicone acrylic thermal pads are high performance based thermal materials that aid in the dissipation of heat from intended targets to cooler surface areas within an electronic device. Acrylic (non-silicone) thermal management materials are often used to cool SSD (solid state drives) or can be attached to the bottom of heatsinks, to act as a thermal interface bridge between surfaces to accommodate thermal conductivity to alleviate over-heating of an electronic device.
In addition, non-silicone thermal conductive pads provide excellent conformability, while also providing gap-filling properties that are enhanced by their ability to be stacked. To benefit custom designed structures, 3M Thermally Conductive Interface Pads can be die cut and laser cut into specific dimensions and are capable of being used in most electronic applications.

Effective Benefits of 3M Acrylic Thermal Conductive Pads

Due to their inherent softness, acrylic thermal interface pads can decrease the load to integrated circuit chips during compression, while exhibiting good tack to many surfaces. Since much of 3M non-silicone thermal interface pads are designed with filled acrylic polymer, they are a perfect solution to silicone sensitive applications. Non-Silicone thermal management materials provide an operative and proper way to transfer heat between active thermal components and heat sinks. Some of the advantages of utilizing acrylic thermal gap pads include:
  • Lower cost when compared to silicone thermal pad equivalents
  • Good softness and conformability to non-flat surfaces
  • No silicone particulation
  • Good surface tack & dielectric performance
  • Excellent durability
  • No siloxane outgassing
  • Halogen-free
  • No silicone oil bleed
  • UL-94 V-O certified
  • Short Lead Times and readily available

Silicone vs Non-Silicone Thermal 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 (non-silicone) thermal management materials are a preferred solution for electronic applications. Non-silicone 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.
Non-Silicone 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 provides 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 some materials able to withstand temperatures up to 200C. However, in an electronic application that temperature range is generally unnecessary. Silicone thermal pads can be extremely soft for conformability challenges.

Non-Silicone Acrylic Material & Conductive Thermal Interface Pad Applications

The most useful contact between the pad and the device can be achieved by utilizing a dry, clean and well-unified surface. The best pre-application treatment chemicals are either rubbing alcohol or heptane, with the ideal application temperature range of 0° to 40° C.
Acrylic thermal based interface pads can be used within a wide range of electronic applications that require heat transfers from a warmer source to a cooler location. Typically Acrylic thermal solutions are effective for short periods to 135C. 
Some of the applications that can benefit from the use of thermally conductive acrylic pads include:
  • Heat sink interface
  • Solid State Drives
  • LED boards
  • IC packaging
  • Gap filling
  • HD TV’s
  • Scan module boards
  • COF chip heat conduction processes
