21. A floor panel for forming a floor covering, wherein the floor panel comprises a layer-shaped substrate, and a decorative top layer situated above the substrate; and wherein the substrate comprises at least a layer formed by a composition comprising at least a thermoplastic synthetic material being polyester;
wherein the thermoplastic polyester is selected from the group comprising polyethylene terephthalate (PET), polybutylene terephthalate (PBT), polytrimethylene terephthalate (PTT), polyethylene naphthalate (PEN), and combinations thereof; wherein the composition also comprises at least a filler including chalk, limestone and/or talc, wherein an amount thereof in the composition is situated between 10 wt % and 80 wt %;
wherein an amount of thermoplastic polyester in the composition is situated between 5 wt % and 50 wt %;
wherein the floor panel, on at least two opposite edges, is provided with mechanical coupling means or coupling parts, wherein these coupling means or coupling parts allow that two of such floor panels can be coupled to each other in such a manner that a locking is created in a direction perpendicular to a plane of the coupled floor panels, and in a direction perpendicular to the coupled edges and in the plane of the coupled floor panel.
