Polymethyl methacrylate (PMMA) is the most important application for methyl methacrylate (MMA). Once cast or moulded it is clear, hard, UV transparent and resistant to gamma rays. Around 40-45% of usage goes to the automotive industry, with 33% used in the building and lighting industry and the remainder used for various applications including CD production, toys, pens, furniture and electronics.
PMMA is available as a white powder or clear plastic sheet, is stable and non-hazardous, but incompatible with strong oxidising agents. It is combustible and in powder form is harmful by ingestion or inhalation.
