Abstract
The present invention discloses a surface covering, in particular a floor or wall covering including a substrate A and a scuff resistant polymer layer B, having an upper and a lower surface, where the polymer layer B includes one or more polymer(s) C, the one or more polymer(s) C having more than 93.5% by weight of cellulose ester polymer(s), where the lower surface of polymer layer B contacts and adheres to the upper surface of substrate A.
Claims20
A surface covering, comprising:
- a substrate (A), having an upper and a lower surface, said substrate (A) being characterized by a deformation of less than 40 degrees as measured for a rectangular substrate (A) sample with dimensions of 160 mm×450 mm, partially contacting and fixed in a horizontal position to a plate support, so that exactly a 160×300 mm part of said sample exceeds the edge of the plate support and is free of support during the deformation measurement,
- the deformation being recorded 30 seconds after removing means that prevent a deformation of the 160×300 mm part under the influence of its own weight,
- the deformation, being the angle, in degrees, between the horizontal position and the position after 30 seconds, of the extreme bottom edge of the freely suspended 160×300 mm part of said rectangular substrate sample (A), free of support and deforming under its own weight away from the horizontal position;
- a scuff resistant polymer layer (B) having an upper and a lower surface, said polymer layer (B) comprising one or more polymers (C), said one or more polymers (C) comprising more than 93.5% by weight of one or more cellulose ester polymers;
- the lower surface of polymer layer (B) contacting and adhering to the upper surface of substrate (A),
- wherein substrate (A) comprises a layer selected from the group consisting of polymer, natural stone, agglomerated stone, ceramic, metal, fibrocement plate, hybrid polymer composite material and combinations thereof,
- and wherein the surface covering comprises a top-layer (D) contacting and adhering to the upper surface of scuff resistant polymer (B).
