One-Sentence Definition
Plexiglass is a transparent acrylic plastic, technically known as polymethyl methacrylate (PMMA), widely used as a lightweight and shatter-resistant alternative to glass. (Merriam-Webster, Acme Plastics)
Detailed Explanation
Plexiglass, originally a trademarked brand (Plexiglas®), has become a generic term for clear acrylic sheets made from PMMA. Developed in the 1930s, it is valued for its high optical clarity, impact resistance, and versatility. Unlike traditional glass, plexiglass is lighter, less likely to shatter, and can be easily cut, shaped, and colored. It is available in various forms—sheets, rods, tubes—and finishes, including frosted, mirrored, and textured. Today, plexiglass is used in everything from retail displays and protective barriers to furniture and signage.
