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. The material is scratch resistant and stands up to outdoor use better than polycarbonate. It maintains clarity over time and won't weaken from exposure to UV, though the pigment in colored acrylic will fade over time when exposed to direct sunlight.
