Acrylic, continuous cast

Acrylic, con­tin­u­ous cast, or extruded [Acrylite® FF, Lucite® Optix®, Per­spex®, Plex­i­glas®]

Prop­er­ties

  • Con­tin­u­ously processed, high-quality acrylic sheet
  • Crys­tal clear, impact– and weather-resistant
  • Light­weight for easy trans­porta­tion and storage
  • High mol­e­c­u­lar weight for supe­rior ther­mo­form­ing, bend­ing and flame polishing
  • Avail­able in col­ored, impact-modified, green-edged and pat­terned sheet
  • Spe­cial ultra­vi­o­let sta­bi­liza­tion pro­tects against yellowing
  • Backed by a 10-year lim­ited warranty
  • Many times stronger, yet much lighter, than glass
  • Continuous-cast acrylic is more eco­nom­i­cal than cell-cast acrylic but has lesser phys­i­cal prop­er­ties and transparency

Com­mon uses

  • Fab­ri­ca­tion and glaz­ing applications
  • Sig­nage, sky­lights, light­ing, awnings and displays
  • Indoor and outdoor
