<p>Multilayer transparent, antireflex, coloured or opaline plates, with smooth or embossed surfaces, optionally thermouldable with external layers in acrylic polymers, low thickness, in the range of 1.5 up to lower thicknesses of 10 mm, by employing one or more polymeric continuous films which have the property to have elastic modulus lower than the one of PMMA of at least 30%, and/or elongation at break higher than at least 40%, measured by the test according to ISO 527 for plates or films, placed inside the panel.</p> |
