Poly(methyl methacrylate) (PMMA) is a clear, colorless polymer used
extensively for optical applications. It is available commercially
in both pellet and sheet form. Outstanding properties include
weatherability and scratch resistance. The most serious
deficiencies are low impact strength and poor chemical resistance
