## Description

This Thermal Gap Filler provides 1.1W/mK of thermal conductivity that can conform to most surfaces. It’s perfect for high-value products that you need to keep cool, as it is a poor conductor of electricity while remaining a great conductor of heat! No additional adhesive is required when applying the Thermal Gap Filler, as it is naturally tacky and sticks to whatever you need it to — just be sure that’s where you need it!

This gap filler is what we use on our Stepoko motion controller as well as what we recommend to use with our [ESP32 Thing Power Control Shield](https://core-electronics.com.au/search/?q=14155), as it is both electrically insulating and stable from -40°C to 160°C while meeting a [UL 94 VO rating](https://en.wikipedia.org/wiki/UL_94).

**Features:**

- Soft and compressible for low-stress applications
- Naturally tacky, needing no further adhesive coating
- 1.1 W/mK thermal conductivity
- Comes in 9"x9" sheets
