For heated presses, our PRESSTHERM material offers a bespoke solution especially for the wood industry and for rubber production.

To meet the high requirements such as temperature stability, chemical resistance, low thermal conductivity and electrical insulation in the demanding production settings, we developed the PRESSTHERM material, which has been reliably in use for decades.

Aspects such as fire protection, manufacturing costs and low setting behaviour were also considered during the development process.

Long service lives guarantee 24/7 production at constant high temperatures and enormous pressure – the toughest requirements placed on the materials used.


  • High temperature pressure resistance
  • Low heat conductivity
  • Chemical resistance
