Quick Summary

Methacrylate refers to a salt or ester of methacrylic acid, or to an acrylic resin or plastic derived from it. It is a key component in the production of polymethyl methacrylate (PMMA), a transparent and rigid plastic often used as a substitute for glass. PMMA is known for its clarity, flexibility, and durability, making it suitable for applications like windows, skylights, signs, and aircraft canopies.12

Methacrylates are part of the broader family of acrylics, which are synthetic resins and fibers based on derivatives of acrylic and methacrylic acid. These materials have a history of development dating back to the early 20th century, with significant commercialization occurring in the 1930s.34
