Video Demo: Thermal Resistivity and Conductivity of Silicone Foam

Thermal resistivity and thermal conductivity can be two very important physical features of foam materials for certain applications. Most devices containing electronic components must be designed to deal with heat in one way or another. Electronic circuitry operates most reliably at lower temperatures.  High operating temperatures decrease the service life of the device or module. It is critical for designs to either conduct or isolate heat away from delicate components to ensure ideal operating temperatures.

While there are many materials that can be used to either conduct or resist heat, this blog post focuses on silicone foam and sponge materials. Silicone foam and sponge maintain all performance characteristics at a wide temperature range, from -60ºF to 500°F (this varies based on the product).  This feature makes silicone foam and sponge materials ideal for high heat applications.  

Common Applications for Silicone Foam/Sponge Materials

  • Indoor and Outdoor LED Lighting
  • Telecommunications Outdoor Enclosures
  • Outdoor Enclosures
  • Electronic Devices
  • Asset Tracking

In order to demonstrate the thermal resistivity and thermal conductivity properties of silicone foam and sponge materials, we decided to create the video below. This video demonstration utilizes Rogers BISCO BF1000 Silicone Foam and Saint Gobain Thermacool R10404 Silicone Sponge. Oh.... and two pieces of cheese.

Check out the video to view the physical properties of these foams.
