PROBLEM TO BE SOLVED: To provide a panel / product exhibiting excellent crush resistance against fracture and / or improved mechanical properties. SOLUTION: One or more polymers installed in the panel and having an elastic modulus at least 30% lower than PMMA and / or a breaking elongation at least 40% higher than that of PMMA, as measured by a test according to ISO527 standard for plates or films. A transparent or anti-reflective, or colored or opalescent multilayer having a smooth or embossed surface comprising a continuous film and optionally a thermoformable outer layer of an acrylic polymer, having a low thickness in the range of 1.5-10 mn. plate. |
