Polymethyl methacrylate (PMMA), also known as acrylic or acrylic glass, is a transparent thermoplastic often used in the form of sheets as an easy alternative to shatterproof glass. Although not a type of known silica-based glass, the material, like many thermoplastics, is often technically classified as a type of glass (in the sense that it is a non-crystalline glassy material) and is therefore referred to as acrylic glass.

PMMA is an economical alternative to polycarbonate (PC), where tensile strength, flexural strength, transparency, polishability and UV tolerance are more important than impact strength, chemical resistance and heat resistance. In addition, PMMA does not contain potentially harmful bisphenol subunits found in polycarbonate and is a much better choice for laser cutting. It is often preferred due to its mild properties, easy handling and processing, and low cost. Unmodified PMMA behaves brittle under load, especially impact strength, and is more prone to scratching than conventional inorganic glass, but modified PMMA is able to achieve high scratch and impact resistance.
