FIELD: chemistry.SUBSTANCE: invention relates to a PVC-free floor or wall covering comprising at least one layer of a thermoplastic composition. The composition contains a polymer matrix comprising at least two polymers and at least 100 pts.wt of least one filler per 100 pts.wt of the polymer(s). Said matrix contains 10-40 pts.wt of a polymer with carboxylic acid anhydride groups in amount of 0.5-3.1 wt %, and the other polymer of the matrix is selected from a group comprising EVA, EMA, EBA, EEA, EPM, EPDM, VLDPE, LLDPE, POE, POP and mixtures thereof, and has melt flow index between 0.6 and 3 g/10 min at 190°C and mass of 2.16 kg. The total amount of combined polymers in the composition is 100 pts.wt.EFFECT: floor or wall covering obtained according to the invention preferably in form of rolls or tiles has improved residual indentation properties and is also suitable for recycling.14 cl, 7 dwg, 9 tbl |
