Abstract
A floor panel may include a substrate and a top layer located above the substrate. The substrate may include a closed cell foamed synthetic material layer with fillers. The closed cell foamed synthetic material layer may have an average density of more than 300 kilograms per cubic meter. The top layer may include 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. The back layer may include a vinyl compound with fillers. The back layer may have a thickness of at least 45 percent of the thickness of the top layer. The floor panel may be rectangular and oblong and may include a pair of long edges and a pair of short edges. The floor panel may include first mechanical coupling parts at the pair of long edges and second mechanical coupling parts at the pair of short edges. The first mechanical coupling parts may allow a horizontal and vertical locking of two of such floor panels using a turning movement along the respective long edges. The first mechanical coupling parts may include a tongue and a groove. The groove may be flanked by an upper lip a…
