Plexiglas is a plastic material formed from polymers of methyl methacrylate (MMA), an ester of methacrylic acid, also known by the trade names Perspex, Acrylite, Acrylplast and Lucite.

This material was developed in 1928 in various laboratories and brought to market in 1933 by the German Röhm industry. It is usually very transparent, more so than glass to the point that it possesses behavior characteristics comparable to optical fiber, in terms of transparency qualities, and with the property of being more or less in different percentages, unbreakable depending on its “compound.” Because of these characteristics, it is used in the manufacture of safety glass and similar items, in accident-prevention devices, and in decorative or architectural objects in general.
