Low-intensity UV effects on optical constants of PMMA film
PMMA is a strong, tough, and lightweight material. It has a density of 1.17–1.20 g/cm , which is less than half that of glass. It also has good impact strength, higher than both glass and polystyrene; however, PMMA's impact strength is still significantly lower than polycarbonate and some engineered polymers. PMMA ignites at 460 °C (860 °F) and burns, forming carbon dioxide, water, carbon mon… WebNov 1, 2015 · Polymethylmethacrylate (PMMA) with a refractive index np = 1.49 [23] was chosen as the material of the dielectric particle.
