Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
1 - 51 . (canceled) 52 . A wear resistant foil comprising a first foil comprising a first thermoplastic material and a second foil comprising a second thermoplastic material, wherein wear resistant particles are arranged between the first and second foils. 53 . The wear resistant foil according to claim 52 , wherein the wear resistant particles are enclosed by the first and the second foil. 54 . The wear resistant foil according to claim 52 , wherein the first thermoplastic material comprises polyvinyl chloride (PVC). 55 . The wear resistant foil according to claim 52 , wherein the second thermoplastic material comprises polyurethane (PU). 56 . The wear resistant foil according to claim 52 , wherein the wear resistant particles comprise aluminium oxide. 57 . The wear resistant foil according to claim 52 , wherein the wear resistant particles have an average particle size of less than 45 μm. 58 . The wear resistant foil according to claim 52 , wherein the wear resistant particles do not protrude from a surface of the second foil opposite the first foil. 59 . The wear resistant foil according to claim 52 , wherein the wear resistant foil is substantially transparent. 60 . The wear resistant foil according to claim 52 , wherein a thickness of the second foil is less than 75 μm after pressing. 61 . 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 and a second foil comprising a second thermoplastic material, and wherein wear resistant particles are arranged between the first and the second foil. 62 . The building panel according to claim 61 , wherein the wear resistant particles are enclosed by the first and the second foil. 63 . The building panel according to claim 61 , wherein the first thermoplastic material comprises polyvinyl chloride (PVC). 64 . The building panel according to claim 61 , wherein the second thermoplastic material comprises polyurethane (PU). 65 . The building panel according to claim 61 , wherein the wear resistant particles comprise aluminium oxide. 66 . The building panel according to claim 61 , wherein the wear resistant particles have an average particle size of less than 45 μm. 67 . The building panel according to claim 61 , 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. 68 . The building panel according to claim 61 , further comprising a decorative layer arranged on the core, wherein the wear resistant foil is arranged on the decorative layer. 69 . The building panel according to claim 61 , wherein a thickness of the second foil is less than 75 μm after pressing.
