Claims10
A building panel comprising a core and a surface layer, wherein the core comprises a mix of thermoplastic material and fillers, the surface layer comprises a composite material comprising wood particles bonded to each other by a cured thermosetting resin, and wherein the surface layer is bonded to the core by the cured thermosetting resin,
- wherein the panel is formed by:
- providing the core by forming a mat-shaped layer comprising a dry blend of fillers and thermoplastic particles under heat and pressure,
- applying the surface layer comprising a powder mix comprising wood particles and thermosetting resin on the core, and
- laminating the surface layer in a pressing operation to the core and thereby forming a building panel, wherein the wood particles of the surface layer and the fillers of the core are bonded to each other by cured thermosetting resin.
