Abstract

A method to produce a wear resistant foil, including providing a first foil including a first thermoplastic material, applying wear resistant particles on the first foil, applying a second foil including a second thermoplastic material on the first foil, and adhering the first foil and the second foil to each other to form a wear resistant foil.

Claims (29)

1. A wear resistant foil comprising:

a first foil comprising a first thermoplastic material;

a second foil comprising a second thermoplastic material; and

wear resistant particles,

wherein all of the wear resistant particles are arranged between the first and second foils, wherein all of the wear resistant particles are enclosed by the first and the second foil,

wherein the wear resistant foil does not have any wear resistant particles which are not: (i) between the first and second foils and (ii) enclosed by the first and second foils.

2. The wear resistant foil according to claim 1 , wherein the first thermoplastic material comprises polyvinyl chloride (PVC).

3. The wear resistant foil according to claim 1 , wherein the second thermoplastic material comprises polyurethane (PU).

4. The wear resistant foil according to claim 1 , wherein the wear resistant particles comprise aluminium oxide.

5. The wear resistant foil according to claim 1 , wherein the wear resistant particles have an average particle size of less than 45 μm.

6. The wear resistant foil according to claim 1 , wherein the wear resistant particles do not protrude from a surface of the second foil opposite the first foil.

7. The wear resistant foil according to claim 1 , wherein the wear resistant foil is substantially transparent.

8. The wear resistant foil according to claim 1 , wherein the wear resistant foil is formed by pressing the first foil and the second foil together, wherein a thickness of the second foil is less than 75 μm after pressing.

9. A building panel comprising:

a core; and

a wear resistant foil arranged on the core,

wherein the wear resistant foil comprises:

a first foil comprising a first thermoplastic material;

a second foil comprising a second thermoplastic material; and

wear resistant particles, and

wherein all of the wear resistant particles are arranged between the first and the second foil, wherein all of the wear resistant particles are enclosed by the first and the second foil,

wherein the wear resistant foil does not have any wear resistant particles which are not: (i) between the first and second foils and (ii) enclosed by the first and second foils.

10. The building panel according to claim 9 , wherein the first thermoplastic material comprises polyvinyl chloride (PVC).

11. The building panel according to claim 9 , wherein the second thermoplastic material comprises polyurethane (PU).

12. The building panel according to claim 9 , wherein the wear resistant particles comprise aluminium oxide.

13. The building panel according to claim 9 , wherein the wear resistant particles have an average particle size of less than 45 μm.

14. The building panel according to claim 9 , wherein the core comprises polyvinyl chloride (PVC), polyester, polypropylene (PP), polyethylene (PE), polystyrene (PS), polyurethane (PU), polyethylene terephthalate (PET), polyacrylate, methacrylate, polycarbonate, polyvinyl butyral, polybutylene terephthalate, or a combination thereof.

15. The building panel according to claim 9 , further comprising a decorative layer arranged on the core, wherein the wear resistant foil is arranged on the decorative layer.

16. The building panel according to claim 9 , wherein the wear resistant foil is formed by pressing the first foil and the second foil together, wherein a thickness of the second foil is less than 75 μm after pressing.
