Abstract
The invention relates to a method for producing a low-exuding preferably non-exuding polymer-bonded phase-change material composition containing phase-change material, characterized in that the phase-change material is liquefied, the liquid phase-change material is introduced into an extruder at a temperature of between 50° C. and 130° C., however at least 20° C. to 70° C. above the melting point of the phase-change material into which the polymer is also introduced, wherein the extruder comprises mixing transport and holder elements and the introduction of the phase-change material into the extruder in the extrusion direction is performed after the polymer.
