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.

A panel comprising:
- at least a substrate of thermoplastic material;
- a top layer with a printed decor;
- and
- a translucent or transparent wear layer,
- wherein said substrate has a thickness larger than one half of a thickness of the entire panel, and
- wherein said substrate at least comprises two layers;
- said two layers each comprising thermoplastic material, wherein a first one of said two layers further comprises at least 60 percent by weight of filler materials and a second one of said two layers comprises less fillers or is not filled, and is situated above said first one of said two layers.
A panel comprising:
- at least a substrate of thermoplastic material having a thickness of 1.3 to 10 millimeter, and
- a top layer with a printed decor and a translucent or transparent wear layer,
- wherein said thermoplastic material is chosen from the list consisting of polyvinylchloride, polypropylene, polyethylene and polyurethane and the thickness of the panel is for more than one half formed by said substrate,
- said panel being a floor panel for a floating floor covering and comprising at two or more opposite edges coupling parts with which two of such floor panels can be coupled at said edges in such a manner that they are mutually locked in a horizontal direction perpendicular to the respective edge and in the plane of the floor panels, as well as in a vertical direction perpendicular to the plane of the floor panels,
- wherein said substrate at least comprises two layers, said two layers each comprising thermoplastic material chosen from the list consisting of polyvinylchloride, polypropylene, polyethylene and polyurethane;
- wherein a first one of said two layers further comprises filler materials and a second one of said two layers comprises less filler materials or is not filled, and is situated above said first one of said two layers and wherein said second one of said two layers forms a surface layer of said substrate upon which said decor is provided.
