Acrylic

Acrylic (PMMA) (polymethyl methacrylate) is both a thermoplastic and transparent plastic. Two of the most common brand names are Plexiglass and Lucite and it is also commonly known as acrylic glass, acrylic, perspex or plexiglas. It is often used as an alternative to glass and is preferred for many applications because of its moderate properties, easy handling, easy processing and low cost. However, acrylic is not recommended for use in structural applications because of its poor impact resistance.
