Polymethyl methacrylate (abbreviated PMMA) is a plastic material made from polymers of methyl methacrylate, methyl ester of methacrylic acid. It is a thermoplastic polymer.
It is also known by the trade names of Plexiglas (only one s), Perspex, Amanite, Lucite, Trespex, Vitroflex, Acrivill, Perclax, Limacryl, Crylux, Oroglas, Setacryl, Altuglas.
It is normally very transparent, more so than glass, can be recycled, has a higher breaking point than glass, is softer and more sensitive to scratches and abrasions; this is generally remedied with an appropriate covering; any scratches can be easily eliminated thanks to specific polishes, unlike glass it does not block ultraviolet and infrared light, it can be cold welded using cyanoacrylate-based adhesives or by dissolving the surface layers with a suitable solvent - dichloromethane or chloroform. The joint created is almost invisible. The sharp edges of the PMMA can also be easily polished and made transparent. PMMA burns in the presence of air at temperatures above 460 °C; its complete combustion produces carbon dioxide and water.
Not to be confused with polymethylacrylate, a polymer that looks like a soft rubber.
