Methyl methacrylate, the highly flammable organic compound at the center of the chemical crisis in Garden Grove, California, is widely used to manufacture resins and acrylic plastics, such as Plexiglas. In liquid form, it has an acrid, fruity odor; after production, it is found in products like advertising signs, light fixtures, plumbing and latex paint. The chemical is also used to make bone cement for orthopedic procedures, as well as dental crowns and fillings.
