Thermal Effusivity of Mousepad

Thermal Effusivity of Mousepad

Sample Material: Polyester and Gel
Sample thickness: 5 mm
Method: TPS-EFF
Measured result at 25°C (2 secs): 135.7 W√s/m2K
Measured result at 25°C (10 secs): 159.1 W√s/m2K

Thermtest wrist-rest mousepad was measured with TPS-EFF. This method allows testing a material for the feel of cool or warmth on fabrics, textiles and solids. The feeling of thermal effusivity is different from test time (touch-times) of 2 and 10 seconds as the material is not the same through-out the thickness. There is a lower effusivity layer on top of a higher thermal effusivity layer, the first 2 seconds feel like 135, followed by an increase of thermal effusivity.
