AcrylicPolymethyl methacrylate (PMMA) is a Thermoplastic and transparent Plastic. Chemically, it is the synthetic Polymer of methyl methacrylate. It is sold by the tradenames Plexiglas, Vitroflex, Limacryl, R-Cast,Per-Clax, Perspex, Plazcryl, Acrylex, Acrylite, Acrylplast, Altuglas, Polycast, Oroglass and Lucite and is commonly called acrylic glass or simply acrylic. The material was developed in 1928 in various laboratories and was brought to market in 1933 by Rohm and Haas Company.
PMMA is often used as an alternative to glass, and in competition with Polycarbonate (PC). 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. To produce 1 kg of PMMA, about 2 kg of petroleum is needed. PMMA ignites at 460°C and burns completely to form only carbon dioxide and water.
