Floor panel

A floor panel comprising:

• a substrate;
• and
• a top layer located above the substrate;
• wherein the substrate includes a closed cell foamed PVC layer with fillers;
• wherein the closed cell foamed PVC layer has an average density of at least 500 kilograms per cubic meter;
• wherein the closed cell foamed PVC layer has a local density on the flat side which is situated closest to the top layer, which is higher than in the center of the closed cell foamed PVC layer;
• wherein the top layer includes a back layer, a printed synthetic material film located above the back layer, and a transparent or translucent synthetic material wear layer located above the printed synthetic material film;
• wherein the back layer includes a vinyl compound with fillers;
• wherein the back layer has a thickness of at least 45 percent of the thickness of the top layer;
• wherein the floor panel is rectangular and oblong and includes a pair of long edges and a pair of short edges;
• wherein the floor panel includes first mechanical coupling parts at the pair of long edges and second mechanical coupling parts at the pair of short edges;
• wherein the first mechanical coupling parts allow a horizontal and vertical locking of two of such floor panels using a turning movement along the respective long edges;
• wherein the first mechanical coupling parts include a tongue and a groove;
• wherein the groove is flanked by an upper lip and a lower lip;
• wherein the first mechanical coupling parts include a vertical locking mechanism having a vertically active locking surface at the upper side of the tongue and the lower side of the upper lip, respectively;
• wherein the first mechanical coupling parts include a horizontal locking mechanism having a horizontally active locking surface at the lower side of the tongue and the upper side of the lower lip, respectively;
• and
• wherein the horizontally active locking surfaces are formed in the material of the closed cell foamed PVC layer.

A floor panel comprising:

• a substrate;
• and a top layer located above the substrate;
• wherein the substrate includes a closed cell foamed PVC layer with fillers;
• wherein the closed cell foamed PVC layer has an average density of more than 300 kilograms per cubic meter;
• wherein the floor panel includes a glass fiber layer located at a distance from the center of the closed cell foamed PVC layer;
• wherein the top layer includes a back layer, a printed synthetic material film located above the back layer, and a transparent or translucent synthetic material wear layer located above the printed synthetic material film;
• wherein the back layer includes a vinyl compound with fillers;
• wherein the back layer has a thickness of at least 45 percent of the thickness of the top layer;
• wherein the floor panel is rectangular and oblong and includes a pair of long edges and a pair of short edges;
• wherein the floor panel includes first mechanical coupling parts at the pair of long edges and second mechanical coupling parts at the pair of short edges;
• wherein the first mechanical coupling parts allow a horizontal and vertical locking of two of such floor panels using a turning movement along the respective long edges;

• wherein the first mechanical coupling parts include a horizontal locking mechanism having a horizontally active locking surface at the lower side of the tongue and the upper side of the lower lip, respectively;
• and
• wherein the horizontally active locking surfaces are formed in the material of the closed cell foamed PVC layer.
