Abstract
A floor panel with a substrate and a decoration provided thereon. The substrate includes at least a foamed layer of thermoplastic material and at least a reinforcement layer. Additionally, a method for manufacturing such floor panels with a substrate and a decoration, where the substrate includes at least a foamed layer of thermoplastic material and at least a reinforcement layer.
Claims19
A floor panel with a substrate and a decoration provided thereon, said decoration comprising a printed motif, wherein the substrate comprises at least a first and a second substrate layer;
- wherein said first substrate layer is a layer of foamed polyvinyl chloride which comprises at least 30 phr of filler materials, and comprises a first content of plasticizers of 0 to 12 phr;
- said first substrate layer being positioned centrally in the substrate, thus forming at least a substrate portion present in a center of a thickness of the substrate;
- said first substrate layer forming at least 30 percent of the thickness of said substrate;
- wherein said second substrate layer is a layer of plasticized polyvinyl chloride wherein said second substrate layer comprises a second content of plasticizer larger than said first content;
- wherein said second substrate layer is positioned between said first substrate layer and said decoration;
- wherein said first substrate layer is a foamed layer obtained at least by means of a chemical foaming process, wherein the polyvinyl chloride comprises hollow spaces filled with a gaseous reaction product remaining present in the form of bubbles.
A floor panel with a substrate and a decoration provided thereon, said decoration comprising a printed motif applied to a thermoplastic foil, wherein said floor panel further comprises a translucent or transparent wear layer provided above said decoration;
- wherein the substrate comprises at least a first and a second substrate layer;
- wherein said first substrate layer is a layer of closed cell foamed polyvinyl chloride which comprises at least 30 phr of filler materials, and comprises a first content of plasticizers of 0 to 12 phr;
- said first substrate layer being positioned centrally in the substrate, thus forming at least a substrate portion present in a center of a thickness of the substrate;
- said first substrate layer forming at least 30 percent of the thickness of said substrate;
- wherein said filler materials comprise mineral filler materials selected from chalk and talc;
- wherein said second substrate layer is a layer of plasticized polyvinyl chloride wherein said second substrate layer comprises a second content of plasticizer larger than said first content;
- wherein said second substrate layer is positioned between said first substrate layer and said decoration;
- wherein said floor panel on at least two opposite edges if provided with coupling means which allow coupling two of such floor panels together, wherein at the respective edges a locking is effected at least in a vertical direction perpendicular to a plane of the panels, wherein at least one of said edges is provided with a groove, the deepest point of which is situated in said first substrate layer;
- wherein said first substrate layer is a foamed layer obtained using a chemical foaming process, wherein the polyvinyl chloride comprises hollow spaces filled with a gaseous reaction product remaining present in the form of bubbles.
