Acrylic has many different names including Poly(methyl methacrylate) (PMMA). It is also known as acrylic or acrylic glass as well as by many different trade names such as Plexiglas, Acrylite, Lucite, and Perspex to name just a few. Acrylic engineering plastic is transparent, lightweight and shatterproof. This type of engineered plastic is often used as an alternative or replacement to glass, as well as casting resin, a comment in inks and coatings, to name just a few.
