Abstract
The present disclosure relates to a method to produce a wear resistant layer (1) and a method to produce a building panel (10) including a wear resistant layer (1). The wear resistant layer (1) includes a thermoplastic material. The wear resistant layer (1) is provided with portions (5, 6) having different gloss levels. The disclosure also relates to such a building panel (10).

A method to produce a building panel comprising a thermoplastic material having a microstructured top surface, the microstructured top surface having different gloss levels, the method comprising:
- applying a decorative layer onto a core,
- applying the thermoplastic material directly onto the decorative layer, wherein the thermoplastic material comprises wear resistant particles substantially encapsulated into the thermoplastic material, the thermoplastic material optionally further including scratch resistant particles and/or additives,
- pressing a top surface of the thermoplastic material, which has the encapsulated wear resistant particles, against a pressing device having portions with different gloss levels, such that the top surface of the thermoplastic material directly attached to the decorative layer obtains a microstructure with portions having different gloss levels, the thermoplastic material being substantially transparent,
- wherein the microstructure in the top surface of the thermoplastic material has a maximum depth of 30 μm,
- further comprising forming embossed portions in the top surface of the thermoplastic material, the embossed portions each having a depth exceeding 100 μm.
A method to produce a building panel, the method comprising:
- providing a substrate,
- applying a decorative layer onto the substrate,
- applying only a single thermoplastic layer, wherein the single thermoplastic layer is applied directly onto the decorative layer, wherein the single thermoplastic layer consists essentially of a thermoplastic material, wear resistant particles substantially encapsulated into the thermoplastic material, and optionally scratch resistant particles and/or additives, and
- pressing the substrate, decorative layer, and the single thermoplastic layer together, thereby forming a building panel,
- wherein a top surface of the single thermoplastic layer directly attached to the decorative layer, which has the encapsulated wear resistant particles, is directly pressed against a pressing device having portions with different gloss levels, such that the top surface of the single thermoplastic layer obtains portions having different gloss levels after pressing, the single thermoplastic layer being substantially transparent
- wherein the pressing device is one of a pressing cylinder, a pressing belt, and a press plate,
- further comprising forming embossed portions in the top surface of the single thermoplastic layer, the embossed portions in the top surface of the single thermoplastic layer each having a depth exceeding 100 μm.
