Thermal Gap Filler

thermalpads


Thermal Gap Filler Pads are highly efficient heat transfer materials that can conform to surface irregularities and adhere to components of various shapes and sizes, including recessed areas and protrusions. 

These pads are particularly useful in situations where there are variations or unevenness in the space between mating surfaces, as well as surface textures that can affect thermal transfer. The pads have excellent pliability and conformity, making them ideal for filling air gaps and small variations.


There are four grades available, each formulated to provide cost-effective thermal conductivity for specific applications. The pads are available in convenient sheet configurations that can be easily die-cut or hand-slitted.


Even highly polished mating surfaces do not provide reliable contact surfaces. To achieve optimal heat flow and the best thermally conductive path, complete physical contact is necessary. By filling these surface voids with a conformable and thermally conductive gap filler pad, the characteristics of the filled gaps can closely resemble those of a solid metal with the same dimensions.
