Sintra is the industry standard brand name for PVC board. This is a type of rigid sign material made of polyvinyl chloride (PVC) that has been extruded into a smooth sheet. PVC is a closed-cell plastic, meaning it is impermeable to water and air. This makes it rigid and able to withstand high pressure while still being lightweight.
PVC board comes in a pure white with a low gloss matte finishing. This gives printed and painted graphics luminosity and prevents dulled colors. Several different thicknesses are available. For larger signs, a thicker board will give added stability. Standard widths are:
- 1mm
- 2mm
- 3mm
- 4mm
- 5mm
- 6mm
- 10mm
- 19mm
The base board for a Sintra sign is cut into the needed size and shape for the graphic. While many signs are rectangular, PVC can be cut into round and irregular shapes as well. Thinner Sintra board is cut using a CNC router or laser cutter to translate the digital design to a physical cut. Boards of a thickness 10mm and up can be die cut.
