Plexiglass - CAST Acrylic Sheet is optically transparent, unaffected by moisture, and offers a high strength-to-weight ratio, and high light transmittance. Plexiglass - Cast Acrylic sheets can be easily heat-formed without loss of optical clarity. Prolonged exposure to moisture, or even total immersion in water, does not significantly effect the mechanical or optical properties of this outstanding material. Plexiglass Sheets (Acrylic sheets) may vary slightly by brand, but process technique is the more important factor (Cast or Extruded).
Why use CAST Acrylic verses EXTRUDED Acrylic ?
Continuous Service Temp: 180 F (Cast) vs. 160 F (Extruded)
Formability Temp: 340 F to 380 F (Cast) vs 290 F to 320 F (Extruded)
Cast acrylic has a higher molecular weight, therefore it will cut, drill and rout cleaner. As you machine cast acrylic, the shavings will flake off whereas the extruded acrylic shavings can gum up on the tool.
Cast acrylic also offers better glue-joint effectiveness and performs better in laser cutting.
