Clear Scratch- and UV-Resistant Cast Acrylic Sheets, Bars, and Cubes

These cast acrylic sheets, bars, and cubes are often fabricated into tanks, see-through barrier panels, and light fixture lenses. Cast acrylic, which is comparable to Lucite and Plexiglas® Acrylic, is easier to machine than extruded acrylic. This material is scratch and UV resistant; it stands up to outdoor use better than polycarbonate and maintains clarity over time.

Clear Impact-Resistant Polycarbonate Sheets and Bars

Bronze

At only half the weight of glass, these polycarbonate sheets and bars are often used for windows, machine guards, instrument gauge covers, and signs. Polycarbonate is comparable to Lexan, Hyzod, Tuffak, and Makrolon. It has greater impact strength than Plexiglas® Acrylic and can be used in similar applications. Sheets and bars that meet UL 972 are rated as burglar resistant.

Gray and bronze sheets and bars are useful in light-sensitive applications where a see-through material is required.
