Fabricate containers, tanks, and lenses for light fixtures with these scratch- and UV-resistant cast acrylic tubes. Cast acrylic, which is comparable to Lucite and Plexiglas® Acrylic, is easier to machine than extruded acrylic. This material stands up to outdoor use better than polycarbonate and maintains clarity over time.

Clear Scratch- and UV-Resistant Acrylic Tubes

Color: Clear
Temperature Range: -40° to 180° F
Tensile Strength; 9,195-11,030 (Good)
Impact Strength: 0.040 ft.-lbs./in.
Hardness: Rockwell M89-M96 (Hard)
For Use Outdoors: Yes
Specifications Met: UL 94HB

When compared to cast acrylic tubes, these extruded acrylic tubes offer nearly the same performance at a fraction of the cost. Use them for sight gauges and protective covers. This scratch- and UV-resistant material stands up to outdoor use better than polycarbonate and maintains clarity over time.
