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.
Claims18
A floor panel for forming a floor covering, wherein the floor panel comprises:
- a carrier with at least a first layer comprising a first thermoplastic material;
- wherein said first thermoplastic material is polyvinyl chloride free from plasticizers or polyvinyl chloride comprising a plasticizer in an amount up to maximum 20 phr;
- wherein said carrier forms at least 40 percent of the thickness of said floor panel;
- a top layer fused to the carrier, the top layer including at least a decor film with a print and at least a wear layer, wherein said wear layer comprises a polyvinyl chloride film with a provided thereon lacquer layer solidified at least by means of excimer radiation;
- 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 said carrier.

A method for manufacturing a floor panel, wherein said method at least comprises:
- the step of providing a carrier, wherein said carrier has at least a first layer comprising a first thermoplastic material;
- wherein said first thermoplastic material is polyvinyl chloride free from plasticizers or polyvinyl chloride comprising a plasticizer in an amount up to maximum 20 phr;
- the step of providing a top layer to said carrier, wherein said top layer includes at least a decor film with a print and at least a wear layer;
- wherein said wear layer comprises a polyvinyl chloride film;
- wherein a lacquer layer is provided on said polyvinyl chloride film and said lacquer layer is solidified at least by means of excimer radiation;
- the step of providing said floor panel by means of a milling operation 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 said carrier.
