An HPL (high pressure laminate) board consists of a wood fibre or paper core and two top layers. The core of the board consists of several layers of wood fibre and paper impregnated with phenolic resin.
During production, these layers are pressed together under high pressure and at a high temperature. The resin used is a so-called thermoset. This means that the resin hardens under the influence of heat. The pressing compresses the board and creates a very dense and rock-hard board.
HPL panels are firm and have a UV-protective and coloured top layer. HPL panels are weather resistant.
