The difference between cast acrylic sheet and extruded acrylic sheet
Cast Plexiglass Sheet:
This style of plexiglass acrylic is made by a process whereby MMA (methyl methacrylate monomer) liquid is pumped into a mold made from two sheets of glass. Cast plexiglass is the highest quality plexiglass acrylic and more expensive than extruded because it offers the best optical clarity, greater thermal stability, and higher chemical resistance to solvents. Cast plexiglass acrylic has a less consistent sheet thickness with up to +/-10% variation possible across the panel; it is thermo-formable and can be reworked hot, which is not always possible with extruded sheets.
Extruded Plexiglass Sheet:
This style of plexiglass acrylic panels are made by semi-soft melted resin pushed between rollers and cut-to-size. Extruded plexiglass acrylic sheets have a higher tolerance when heated or bent and are typically more malleable than cast plexiglass acrylic sheets. It generally is the best thickness consistency, softest sheet, easy to glue, best for chemical bonding, and the standard material for displays, replacement windows, and some signage applications.
