CR-39: Applications & Standards

Poly(allyl diglycol carbonate) (PADC) is a thermosetting plastic commonly used in the manufacture of eyeglass lenses alongside the material PMMA (polymethyl methacrylate). The monomer is liquid allyl diglycol carbonate (ADC). The term CR-39 technically refers to the ADC monomer, but is more commonly used to refer to the finished plastic.
