polymetylmetakrylaatin

Polymetylmetakrylaat, often abbreviated as PMMA, is a synthetic acrylic polymer. It is a transparent thermoplastic that is often used as a lightweight and shatter-resistant alternative to glass. PMMA is known for its excellent optical clarity, high tensile strength, and resistance to UV radiation. It is also relatively easy to fabricate and process, making it a versatile material for a wide range of applications.

The chemical formula for polymethylmethacrylate is (C5O2H8)n. It is produced through the polymerization of methyl methacrylate monomer. The resulting polymer can be formed into sheets, rods, tubes, and various molded shapes. PMMA is also available in a variety of colors and finishes.

Common trade names for polymethylmethacrylate include Plexiglas, Lucite, and Perspex. These materials are frequently used in the automotive industry for taillights and instrument panels, in construction for skylights and sound barriers, and in the medical field for prosthetics and bone cement. Its applications also extend to consumer goods like aquariums, screens, and decorative items due to its clarity and durability. PMMA is also recognized for its good weathering resistance, maintaining its properties when exposed to sunlight and various environmental conditions.
