thermal conductor film / ceramic / polyimide / flexible

HEATPAD® KU-KG are high-performance thermoconducting films, consisting of a polyimide carrier film filled with thermally conductive ceramic, and a silicone-free CRAYOTHERM® coating on both sides. They combine the outstanding dielectric and mechanical properties of a polyimide with the thermal properties of CRAYOTHERM®. The CRAYOTHERM® coating changes its aggregate state when heated to ca. 60°C, turning soft. Due to its expansion in volume (by 15 to 20 per cent) and the subsequent active covering of the contact surfaces, it compensates for next to all flaws in these surfaces, minimizing thermal transfer resistance. Once the phase-change temperature is first exceeded, the material's optimal thermal performance is sustained at all times, below and above that temperature.
