This opaque 3mm Perspex Acrylic Sheet measures 297mm x 210mm (A4). The surface of the sheet has a high gloss finish. You cannot see through opaque Perspex sheets meaning they can be used in designs/products to provide areas of solid colour.
- High gloss surface.
- Very low light transmission.
- Easily laser cut, drilled and thermoformed.
Opaque Perspex acrylic sheets have many applications such as point of sale, model making, signs, artistic and architectural installation, casings, etc.
Working with Perspex acrylic sheets:
Perspex is a versatile material that can be cut, drilled, laser cut and thermoformed.
Perspex is a thermoplastic which means that when it is heated above 140-180°C it becomes flexible. This allows the material to be formed into the required shape or bent. Once the material cools below 85°C it becomes rigid again.
Perspex sheets are often shaped using a CNC router or laser cutter. The edge of laser cut Perspex has a pleasing polished look. If you look carefully at the edge of a piece of laser cut Perspex you can often see slight vertical lines that are caused by the pulses a laser uses when cutting.
If you want to get a perfectly smooth finish on the edge of piece of machined Perspex a polishing technique can be used. Typical polishing techniques include diamond polishing and flame polishing.
It also possible to etch the surface of a Perspex sheet using a laser cutter. This can produce some very pleasing visual effects. The Perspex sheets have a protective film on both faces. If you are etching the material then this should be removed from the surface that is to be etched. If you are just laser cutting then this film can be left in place (if you wish) as it does not create any harmful gases when it is laser cut (unlike PVC).
