Lichtenberg figure: high-voltage dielectric breakdown in an acrylic polymer block
Poly(methyl methacrylate) (PMMA) is a synthetic polymer derived from methyl methacrylate. It is a transparent thermoplastic used as an engineering plastic. PMMA is also known as acrylic and acrylic glass and by the trade names and brands Crylux, Walcast, Wanjiale, Hesalite, Plexiglas, Acrylite, Lucite, PerClax, and Perspex, among several others (see below). This plastic is often used in sheet form as a lightweight or shatter-resistant alternative to glass. It can also be used as a casting resin, in inks and coatings, and for many other purposes.
