PMMA (Poly Methyl Methacrylate)
This thermoplastic and transparent plastic is commonly called acrylic glass or simply acrylic. PMMA is often used as an alternative to glass, and in competition with polycarbonate (PC). It is often preferred on account of its moderate properties, easy handling and processing, and low cost, but behaves in a brittle manner when loaded, especially under an impact force. PMMA is now also widely used in the electronic and LCD industry.
