Abstract
A polymer floor element includes a decorative top layer on a substrate made of polymer. The floor element has a rectangular or square surface, for which it is valid that for a strip of the floor element with a first point Q defined as a vertex of the strip, and a point P at a distance of 40 cm with respect to Q along a side of the strip, suspended over a rod with diameter 2 cm with its side on which P and Q are defined, perpendicular to the axis of the rod, so that P is located in the vertical direction at the highest point where the floor element touches the rod. The strip, with point Q along one side, hangs down from the rod under the strip's own weight; the straight line PQ intersects the vertical through P at an angle less than 15°.
Claims13
A polymer floor element comprising a decorative top layer on a substrate made of polymer,
- wherein the floor element has a rectangular or square surface with a longest side less than 3.0 m and greater than 0.4 m, for which it is valid that for a strip of the floor element with a first point Q defined as a vertex of the strip, and a point P at a distance of 40 cm with respect to Q along a side of the strip, suspended over a rod with diameter of 2 cm with its side on which P and Q are defined, perpendicular to an axis of the rod, so that
- P is located in a vertical direction at the highest point where the floor element touches the rod;
- and
- the strip, with point Q along one side, hangs down from the rod under the strip's own weight;
- a straight line PQ intersects the vertical through P at an angle less than 15°;
- wherein the floor element is sheet vinyl;
- wherein the sheet vinyl comprises a substrate layer comprising one or more flexible or semi-rigid PVC layers, and a finishing layer including a decorative layer and a wearing layer;
- wherein the wearing layer is a flexible or semi-rigid PVC layer;
- wherein the wearing layer includes more than 30 phr plasticizer;
- wherein the decorative layer is a printed layer, printed directly on the flexible or semi-rigid PVC layer of the substrate laver;
- wherein the flexible or semi-rigid PVC layer of the substrate layer and/or of the wearing layer is applied as a layer by means of PVC plastisol.
A polymer floor element comprising a decorative top layer on a substrate made of polymer,
- wherein the floor element has a rectangular or square surface with a longest side less than 3.0 m and greater than 0.4 m,
- wherein said floor element passes a flexibility test according to ASTM F137 with a cylinder of 6 mm;
- wherein the floor element is sheet vinyl;
- wherein the sheet vinyl comprises a substrate layer comprising one or more flexible or semi-rigid PVC layers, and a finishing layer including a decorative layer and a wearing layer;
- wherein the wearing layer is a flexible or semi-rigid PVC layer;
- wherein the wearing layer includes more than 30 phr plasticizer;
- wherein the decorative layer is a printed layer, printed directly on the flexible or semi-rigid PVC layer of the substrate layer;
- wherein the flexible or semi-rigid PVC of the substrate layer and/or of the wearing layer is applied as a layer by means of PVC plastisol.
