Methyl methacrylate (MMA) is a colorless liquid that is used primarily in the production of plastics and resins. It is a key ingredient in making acrylic glass, which is known for its clarity and durability. MMA is also used in coatings, adhesives, and various other applications due to its ability to polymerize and form strong materials. MMA is produced through the reaction of methanol and acrylonitrile. It is important to handle MMA with care, as it can be harmful if inhaled or absorbed through the skin. Proper safety measures are essential when working with this chemical in industrial settings.
