Poly(methyl methacrylate), often abbreviated as PMMA, is a synthetic polymer made from the polymerization of methyl methacrylate monomers. It is a clear, lightweight plastic that is commonly used as a glass substitute due to its excellent optical clarity and resistance to UV light. PMMA is also known for its durability and weather resistance, making it suitable for outdoor applications. This versatile material is widely used in various industries, including automotive, construction, and medical fields. PMMA can be found in products such as acrylic sheets, lenses, and signage. Its ease of fabrication allows for diverse applications, from decorative items to functional components in electronics.
