PMMA

PMMA or Poly(methyl methacrylate) is a transparent thermoplastic. Its also known by several other names like Lucite, Plexiglas, Optix, Perspex etc. According to Wikipedia, PMMA is an economical alternative to polycarbonate (PC) when extreme strength is not necessary. Additionally, PMMA does not contain the potentially harmful bisphenol-A subunits found in polycarbonate. It is often preferred because of its moderate properties, easy handling and processing, and low cost, but behaves in a brittle manner when loaded, especially under an impact force, and is more prone to scratching compared to conventional inorganic glass. One of the everyday usage of PMMA is lucite flower beads.
