The investigated samples are transparent in the region 800 to 400 nm, except in case of rhodamine B which shows an absorption band at 555 nm. UV photons can have enough energy to ionize an atom or change its chemi-cal structure. No other plastic material can deliver this level of UV transparency performance. The results indicate that changes occurred due to UV-B radiation, such as chain scission and color change, which may lead to a decrease in resistance. These samples were evaluated spectrophotometrically before and after UV-irradiation. Most grades of TOPAS COC also have broad compliance with global food packaging regulations. TOPAS COC is extremely resistant to these and other polar materials that can wreak havoc with many common plastics.
