<p>Floor panel comprising a bottom layer and a top layer, the bottom layer comprising recycled polyurethane. The bottom layer, comprising recycled polyurethane, is waterproof and has a negligible coefficient of expansion. The bottom layer is also temperature-insensitive, thermally and acoustically insulating and shockabsorbing. Compared to a known chipboard bottom layer, the bottom layer according to the invention has a relatively low modulus of elasticity (E = 1000 N/mm) and excellent bending properties, so that the bottom layer can adapt optimally to the expansion and bending of the top layer.</p> |
