Abstract
Panel for forming a floor covering, wherein this panel comprises at least a layer of thermoplastic material, wherein said layer also comprises at least individual fibers having a length greater than 1 millimeter.
Claims16
A panel for forming a floor covering, wherein this panel comprises:
- a substrate layer having a thickness of 1.3 to 10 millimeters, said substrate layer being substantially formed by one or more layers of thermoplastic material,
- wherein this panel, above said one or more layers of thermoplastic material, comprises at least also a printed decor and a translucent or transparent wear-layer,
- with at least one said layers of thermoplastic material situated at least halfway in the thickness of the panel, wherein said thermoplastic material is chosen from the list consisting of polyvinyl chloride, polypropylene, polyethylene, and polyurethane,
- wherein each of said one or more layers of thermoplastic material also comprises at least individual glass fibers having a length greater than 1 millimeter, and wherein said individual glass fibers are loose and freely distributed within each of said layers of thermoplastic material, and
- wherein said panel at one or more edges comprises mechanical coupling parts allowing to couple two of such panels to each other;
- said coupling parts being substantially realized in said substrate layer.

4 more elements
A method for manufacturing panels, wherein said method comprises at least the step of:
- providing a substrate having a thickness of 1.3 to 10 millimeters by at least forming one or more layers of thermoplastic material on the basis of a strewn granulate of said thermoplastic material,
- wherein said one or more layers of thermoplastic material is situated at least halfway in the thickness of the panel, wherein said thermoplastic material is chosen from the list consisting of polyvinyl chloride, polypropylene, polyethylene, and polyurethane,
- wherein each of the formed one or more layers comprises individual fibers having a length greater than 1 mm, wherein said individual glass fibers are loose and freely distributed within each of said layers of thermoplastic material, and
- forming a printed décor and a translucent or transparent wear layer above said layer of thermoplastic material, and
- wherein at one or more edges of said panel, mechanical coupling parts are formed allowing to couple two of such panels to each other, said coupling parts being substantially realized in said substrate layer.
