Acrylic, cell-cast

Acrylic, cell-cast [Acrylite® GP, Plex­i­glas® G, Polycast®]

Prop­er­ties

  • Ver­ti­cally cast between two glass plates
  • Excel­lent chem­i­cal resistance
  • Higher mol­e­c­u­lar weight than continuous-cast acrylic
  • Easy to machine
  • Many times stronger, yet much lighter, than glass
  • Trans­parency equal to opti­cal glass
  • Out­stand­ing sound abatement
  • FDA-approved

Com­mon uses

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