1. A floor panel comprising:
a substrate and a decor provided on the substrate;
wherein on at least one pair of opposite edges of the substrate, coupling parts realized at least partially from the substrate, wherein said coupling parts are configured to effect a mechanical locking between two of such floor panels,
wherein the substrate comprises a rigid substrate layer formed by extrusion of a composition comprising polyvinyl chloride, an amount of filler, an impact modifier and a stabilizer; wherein said rigid substrate layer is free from plasticizers or comprises an amount of less than 5 phr of plasticizers; wherein said amount of filler is at least 60 percent by weight of said rigid substrate layer;
wherein a density of the rigid substrate layer is at least 1300 kg/m3; wherein a thickness of said rigid substrate layer is at least 65% of an overall thickness of said floor panel;
wherein said overall thickness of said floor panel is between 3 and 10 mm, the floor panel showing a modulus of elasticity or Young's modulus of at least 3000 N per square millimeter.
