  • the carrier layer is not destroyed by the acting pressing temperature and the pressing pressure.

  • the pressing pressure is greater than or equal to 25 kg / cm 2 .
  • the pressing temperatures are greater than 100 ° C and less than 200 ° C.

  • the temperature of the lower press plate is 25 ° C and above.
  • the temperature of the lower press plate during the pressing process is greater than 60 ° C.
  • top layer is applied as a powder mixture. Covering in compression by a continuous resin film such as an impregnated overlay film is not required. As a result, condensate moisture arising during pressing can escape more easily. Accordingly, adhesion of the top layer to the carrier layer takes place.
  • product-specific composition of the top layer takes place as a powder mixture of fibrous and / or pulverulent wood material, binders and resins and fillers.
  • the support layer based on polyurethane and the top layer of the powder mixture are prepared separately from each other.
