Polymethyl methacrylate (PMMA) Properties and Their Values

Polymethyl methacrylate (PMMA) is one of the versatile transparent plastics which offers good mechanical and optical properties. Some of these characteristics have enabled it to replace glass inseveral applications. Learn more about all PMMA properties and their values - ranging from mechanical to electrical to chemical properties, to make right selection for your application.
