GS (cast acrylic) is optically purer, but has a thickness tolerance*. XT (extruded acrylic) has hardly any thickness tolerance, but is optically slightly less pure. However, the optical differences are hardly noticeable, especially with smaller sheets.
For applications where the material is in a profile or where a flat surface is required, we recommend using extruded acrylic. Because XT acrylic is produced in large quantities, XT acrylic sheets are relatively slightly cheaper than cast GS acrylic sheets.
Want more choice of thicknesses, colours and surfaces? Then you can opt for cast (GS) acrylic.
*a difference in the thickness within a sheet. For cast acrylic, the standard for A-grade is +/- 0.4mm +10% nominal thickness, so a 10mm sheet runs from 8.6 to 11.4mm. Within one sheet!
Acrylic is crystal clear, 25 times stronger than glass and available in many colours, thicknesses and surface textures. Acrylic has the EN13501 fire classification. Acrylic is very easy to process: sawing, milling, laser cutting, hot and cold bending, gluing, drilling, polishing, sanding and printing.

Polycarbonate is highly impact-resistant and 250 times stronger than glass. This material is less clear compared to acrylic. Polycarbonate is available in clear and in some colours. This material has a better fire rating than acrylic: Bs1d0. Polycarbonate cannot always be lasered.
Brand names: Fuerto®, Colorado®, Makrolon® and Lexan®.
PETG is food-grade certified, chemical-resistant and is the only plastic allowed in public areas such as airports. In addition, PETG is impact-resistant and has the same fire certification as polycarbonate. PETG is not UV-resistant. PETG has no thickness tolerance and is available in clear and in some colour variations. PETG can also be vacuum formed. This material cannot always be lasered.
