1. A floor panel for forming a floor covering, comprising a substrate, which substantially consists of a filled synthetic material composite, and a top layer, which top layer has a thickness from 1 to 15 millimeters, wherein the floor panel is rectangular and oblong, and comprises a first pair of opposite sides and a second pair of opposite sides;
wherein said floor panel, at said first pair of opposite sides, comprises first coupling parts, which substantially are performed as a male coupling part and a female coupling part, and which are provided with vertically active locking portions, which, when the first coupling parts of two of such floor panels cooperate with each other, effect a locking in vertical direction, perpendicular to a plane of the coupled floor panels, and also are provided with horizontally active locking portions, which, when the first coupling parts of two of such floor panels cooperate with each other, effect a locking in horizontal direction, perpendicular to the respective sides and in the plane of the coupled floor panels; wherein said floor panel, at said second pair of opposite sides, comprises second coupling parts, which substantially are performed as a male coupling part and a female coupling part, and which are provided with vertically active locking portions and horizontally active locking portions; wherein the female coupling part of said first coupling parts comprises a groove, which is bordered by an upper lip and a lower lip; wherein a majority of the thickness of said upper lip is formed by said top layer, whereas a remainder of said upper lip is formed by said substrate; wherein said filled synthetic material composite comprises a thermoplastic material and an inorganic filling material. |
