Technogel® is a dense material (like water approx. 1000kg/m3). This distinguishes it from other materials that contain air such as flexible foam, latex or memory foam. This density allows Technogel® to absorb heat rather than reflect it like a foam. This heat storage capacity can be calculated and measured by the thermal capacity in kJ. (4.18 kJ = 1 kcal)The amount of gel determines how much heat can be stored. Heat is also transferred from the warmer to the colder body if there is a temperature difference between the two bodies. By releasing heat, we reduce our core temperature and Technogel® helps by absorbing the excess heat rather than reflecting it like a foam.
This is especially important as our body emits approximately 2160kJ of heat/energy during sleep.
