Pressure-resistant insulation for heated presses

The present invention relates to a pressure-resistant insulating element (1) for heated presses, which by a first pressure-resistant body (10) with a recess (11; 11a, 11b), which is formed preferably in the direction of heat flow (W), and a medium , preferably a solid body having a lower thermal conductivity than the first pressure-resistant body (10), is characterized.
