Abstract
A panel including at least a substrate of thermoplastic material and a top layer with a printed decor and a translucent or transparent wear layer. The substrate has a thickness larger than one half of the thickness of the entire panel, and the substrate at least includes two layers, where the two layers each include thermoplastic material. A first one of the two layers further includes at least 60 percent by weight of filler materials and a second one of the two layers includes less fillers or is not filled, and is situated above the first one of the two layers.
Claims20
A panel comprising:
- a substrate formed by thermoplastic material;
- a printed decor film having a lower side located directly on the substrate;
- and
- a translucent or transparent wear layer located on an upper side of the printed decor film,
- wherein said substrate has a thickness larger than one half of an overall thickness of the panel, and wherein said substrate is formed essentially by a first layer and a second layer of thermoplastic material, wherein the first layer forms an underside of said panel, and said lower side of said printed decor film is located directly on said second layer, wherein the first layer is formed by thermoplastic material having a lower amount of plasticizer than the second layer,
- wherein said panel is a floor panel for a floating floor covering, wherein at two or more opposite edges of the panel, coupling parts are formed in that two of the floor panels are arranged to be coupled at the opposite edges to mutually lock in a horizontal direction perpendicular to the respective edge and in the plane of the floor panels, and in a vertical direction perpendicular to the plane of the floor panels,
- wherein said coupling parts are essentially formed from and in said substrate, wherein said coupling parts comprise a tongue and a groove bordered by an upper lip and a lower lip, wherein said lower lip extends beyond said upper lip, and wherein said upper lip is formed in said second layer of said substrate, wherein said lower lip is formed in said first layer of said substrate.
