Polymethylmethacrylate (PMMA) was irradiated (360–811 h) in a UV-B accelerated aging chamber at room temperature and oxidizing atmosphere. TOPAS COC is unaffected by moisture, and because most grades are 100% amorphous, dimensional accuracy is not affected by crystallization as many plastics can be. Idéales pour divers applications telles vitrages, fabrication et design. Le PMMA (Polyméthacrylate de Méthyle) est une plaque coulée ou extrudée combinant qualité optique et résistance aux UV (PMMA extrudé et PMMA coulé). Both types of samples show high transmission above ~400 nm wavelength, which is expected as PMMA finds wide applications as an optically transparent window material. Les paramètres de transmission et de diffusion de la lumière peuvent être modifiés à la demande. While TOPAS COC is highly transparent to UV, it is not particularly resistant to long term UV exposure, because UV stabilizers reduce ultraviolet transmission.
