Abstract

Floor panel for forming a floor covering, where the floor panel includes a carrier on the basis of a thermoplastic material and a top layer provided on the carrier. The thermoplastic material is free from plasticizers or includes a plasticizer in an amount up to maximum 20 phr, where the thermoplastic material is foamed or expanded, and where the carrier is provided with a reinforcement layer.

First claim

The invention claimed is:

1. A floor panel for forming a floor covering, wherein the floor panel comprises:
a carrier consisting of a first layer on the basis of a first thermoplastic material and a single remaining layer thermally laminated to said first layer and formed by means of extrusion of a second thermoplastic material; and
a top layer fused to the carrier, the top layer including at least a printed decor film and a wear layer,
wherein said first thermoplastic material is free from plasticizers or comprises a plasticizer in an amount up to maximum 20 phr,
wherein said first thermoplastic material is foamed or expanded and is reduced in weight of at least 40% of the weight of said first layer, and wherein said first thermoplastic material has a Fikentscher K-value of 85 or below;
wherein said carrier is provided with a reinforcement layer;
wherein said floor panel is provided on at least two opposite edges with coupling means which allow that two of such floor panels can be coupled to each other in such a manner that a locking is obtained in a vertical direction perpendicular to the plane of the coupled panels as well as in a horizontal direction perpendicular to the coupled edges and in the plane of the floor panel;
wherein the coupling means are provided substantially in the first and second thermoplastic materials of the carrier.

2. The floor panel of claim 1 , wherein said reinforcement layer is a glass fiber cloth or glass fiber fleece.

3. The floor panel of claim 1 , wherein said first thermoplastic material comprises plasticizer in an amount between 5 and 15 phr.

4. The floor panel of claim 1 , wherein said top layer comprises a further thermoplastic layer.

5. The floor panel of claim 4 , wherein said printed decor film is a printed synthetic material film.

6. The floor panel of claim 4 , wherein said further thermoplastic layer is a thermoplastic backing layer based on one or a combination of polyvinyl chloride, polyethylene, polypropylene and/or polyurethane, and wherein said backing layer comprises inorganic fillers.

7. The floor panel of claim 5 , wherein said further thermoplastic layer is a thermoplastic backing layer based on one or a combination of polyvinyl chloride, polyethylene, polypropylene and/or polyurethane, and wherein said backing layer comprises inorganic fillers.

8. The floor panel of claim 1 , wherein said thermoplastic material is chosen from the list consisting of polyvinyl chloride, polyethylene, polypropylene, polyurethane and polyethylene terephthalate.

9. A floor panel for forming a floor covering, wherein the floor panel comprises:
a carrier consisting of a first layer on the basis of a first thermoplastic material and a single remaining layer thermally laminated to said first layer and formed by means of extrusion of a second thermoplastic material; and
a top layer fused to said carrier, wherein said top layer comprises a decor and a wear layer,
wherein said first thermoplastic material is free from plasticizers or comprises a plasticizer in an amount up to maximum 20 phr, wherein said first thermoplastic material is polyvinyl chloride having a Fikentscher K-value of 85 or below;
wherein said floor panel is provided on at least two opposite edges with coupling means which allow that two of such floor panels can be coupled to each other in such a manner that a locking is obtained in a vertical direction perpendicular to the plane of the coupled panels as well as in a horizontal direction perpendicular to the coupled edges and in the plane of the floor panels;
wherein the coupling means is provided substantially in the first and second thermoplastic materials of the carrier.

10. The floor panel of claim 9 , wherein said top layer comprises a thermoplastic backing layer based on one or a combination of polyethylene, polypropylene and/or polyurethane, and wherein said backing layer comprises inorganic fillers.

11. The floor panel of claim 9 , wherein said decor is in the form of a print provided on a synthetic material film, wherein said synthetic material film is a polyethylene or a polypropylene film.

12. The floor panel of claim 9 , wherein the first thermoplastic material of said carrier is foamed or expanded.

13. The floor panel of claim 12 , wherein said first thermoplastic material is provided with a reinforcement layer defined as a glass fiber cloth or glass fiber fleece.

14. The floor panel of claim 11 , wherein said wear layer is a polyethylene or a polypropylene film, thermally laminated to said synthetic material film.
