Cast Versus Extruded Acrylic Sheets

The surface finish flatness and optical properties of cast acrylic sheets are all superior to those of extruded acrylic sheets.

Cast versus extruded acrylic sheets.

Difference between cast and extruded acrylic definition. The mould monomer is then submerged in warm water and the process of polymerization takes place. Cast acrylic can be thermally well deformed whereby the deformation properties are homogeneous in all directions. Available in a broad range of standard and custom colors for a variety of applications cast acrylic is more pliable than extruded less likely to bend chip or melt during milling.

In brief they are manufactured by two different production processes. Cast acrylic is generally regarded as a better quality material and offers a number of advantages over the extruded variant such as being more resistant to chemicals and solvents less prone to scratching easier to machine and fabricate and available in a far wider range of colours and surface finishes i e. Extruded acrylic can be easily deformed thermally but there may be differences in deformation properties between longitudinal or transverse orientation to the direction of extrusion. Because extruded material is limited in thickness cast acrylic is a better option for larger structures installations etc.

Laser engraving the laser engraving will on extruded acrylic look. Difference between cast acrylic sheet and extruded acrylic sheets cast acrylic sheets. Cast acrylic as the name suggests is manufactured by a process whereby mma methyl methacrylate monomer liquid is pumped into a mould made from two sheets of glass. Cast acrylic versus extruded acrylic chemical resistance cast acrylic is more resistant to the same solvents.

Cast acrylic materials are available in a wide variety of colors. Cast acrylic is a form of acrylic material that is produced by mixing the acrylic liquid.
