Polymetylmetakrylaatti

Polymetylmetakrylaatti, commonly known as PMMA, is a synthetic thermoplastic polymer. Its chemical formula is (C5O2H8)n. PMMA is often referred to by trade names such as Plexiglas, Lucite, and Acrylite. It is a transparent solid plastic that is more transparent than most types of glass. PMMA is also more shatter-resistant than glass, making it a suitable alternative for many applications.

The production of PMMA typically involves the polymerization of methyl methacrylate (MMA) monomer. This process can be carried out using various methods, including bulk polymerization, suspension polymerization, and emulsion polymerization. The resulting polymer can be processed into sheets, rods, or molding compounds.

PMMA exhibits excellent optical clarity, good weather resistance, and high surface hardness. It is also relatively lightweight and has good impact resistance, although it can be brittle compared to some other plastics. PMMA is resistant to many chemicals but can be attacked by organic solvents.

Due to its properties, PMMA finds widespread use in various industries. It is commonly used in the production of aircraft windows, automotive taillights, signage, lighting fixtures, and protective screens. In the medical field, it is utilized for bone cement, intraocular lenses, and other devices. Its aesthetic qualities also make it popular for decorative items and furniture. PMMA can also be colored, frosted, or made opaque for specific design requirements.
