Abstract: A rigid multilayer decorative surface covering is proposed. The surface covering has a thickness and comprises a sandwiched reinforcement composite layer comprising a thermoplastic polymer matrix having a top and a bottom surface, the sandwiched reinforcement composite layer comprising reinforcement layers on the top and bottom surfaces. The sandwiched reinforcement composite layer has a thickness comprised in the range from 25% to 85% of the thickness of the rigid decorative surface covering. A method for manufacturing the rigid multilayer decorative surface covering is also disclosed.

Abstract: A floor or wall covering panel has a top and a bottom surface, and at least four sides, where a first and a second side include a first and a second connection profile, respectively, the first profile being configured for mechanically engaging and interlocking with the second profile of another panel, the first profile including a tongue protruding beyond the top edge of the first side, where the second profile includes a groove recessed with respect to the top edge of the second side, the groove is delimited at its bottom by a base, the panel is of laminar structure including a rigid core layer and a wear layer arranged on the core layer, where the core layer includes a first and a second sublayer of a first and a second composite material, respectively, the second sublayer being arranged atop the first sublayer, where both composite materials comprise thermoplastic material and filler material but are of different formulations, and the base delimiting the groove bottom is realized essentially within the fir

Abstract: A floor or wall covering panel has a top and a bottom surface, and at least four sides. A first and a second side comprises a first and a second connection profile, respectively. The first profile is configured for mechanically engaging and interlocking with the second profile of another panel. The first profile comprises a tongue protruding beyond the top edge of the first side, whereas the second profile comprises a groove recessed with respect to the top edge of the second side. The groove is delimited at its bottom by a base. The panel is of laminar structure, including a rigid core layer and a wear layer arranged on the core layer. The core layer includes a first and a second sublayer of a first and a second composite material, respectively. The second sublayer is arranged atop the first sublayer. Both composite materials comprise thermoplastic material and filler material but are of different formulations. The base delimiting the groove bottom is realized essentially within the first core sublayer.
