This sample of our 3mm Opaque Frosted Perspex Acrylic Sheet measures 98mm x 98mm. This offers a perfect way of checking the suitability of a material without having to buy a complete sheet first. Check the finish of the material and get the perfect settings for your laser without having to practice on a full-sized/priced sheet.
The surface of the sheet has a double-sided matt surface which gives an effect similar to that of sandblasted or etched glass. The frosted texture is retained after thermoforming. This Frosted Perspex is opaque and offers a solid, dense block of colour with very little light reflection due to the frost finish.
- Easily laser cut, drilled and thermoformed.
- Matt sandblasted effect surface.
- Solid, dense block of colour.
- Very little light reflection.
Frosted Perspex acrylic sheets have many applications such as point of sale, signage, models and display cases, glazing, 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).
More detailed information and resources on working with Perspex can be found in our resource section.

Perspex colour reference code:
- Midnight Black: S29221.
- Moonlight White: S21T41.
- Length: 98mm.
- Width: 98mm.
- Thickness: 3mm (nominal).
The manufacturing tolerance for the thickness of cast Perspex acrylic sheets are the stated thickness +/-10% plus +/- 0.4mm. This means a 3mm Perspex sheet could be between 2.3mm and 3.7mm in thickness.
