Polymethyl methacrylate (PMMA) is a synthetic polymer commonly known as acrylic or acrylic glass. It is a transparent thermoplastic that is often used as a lightweight and shatter-resistant alternative to glass. PMMA is widely utilized in various applications, including lenses, displays, and signage, due to its clarity and durability. PMMA is produced through the polymerization of methyl methacrylate, a liquid monomer. This process creates a solid material that can be easily molded and shaped. Its resistance to UV light and weathering makes it suitable for outdoor applications, while its versatility allows for use in industries such as automotive, construction, and healthcare.
