Additional Specifications |
Widely used to make sight windows and light fixture lenses, these cast acrylic rods and discs maintain clarity over time. 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. Comparable to Lucite and Plexiglas® acrylic, cast acrylic is easier to machine than extruded acrylic.
