What can I use Perspex® acrylic for?
Perspex® acrylic is extremely versatile and can be used in applications as diverse as signs, POS, visual communication, window glazing, acoustics, design, architecture, furniture, boat and car windows, kitchen and bathroom splashbacks - the list is almost endless.
What are the advantages of using Perspex® acrylic sheet? The main advantages of Perspex® acrylic sheets are:
- high shock, abrasion and flex resistance
- excellent weather and UV resistance (applies to clear only)
- low density / light weight compared with glass
- clear sheet offers excellent optical clarity
- comprehensive range of colours and finishes
- 100% recyclability
How is Perspex® acrylic made?
Cast Perspex® acrylic sheet is produced directly from monomer, cast between two sheets of high quality glass and is polymerised in batches in specially developed ovens and water baths in a carefully controlled manufacturing process.
Extruded Perspex® acrylic sheet is produced from the acrylic polymer Lucite Diakon in the form of granules, and extruded into sheet.
How should I cut Perspex® acrylic?
To achieve a good finish on Perspex® acrylic, all cutting tools must be kept sharp. Most hand tools designed for use with wood and soft metals are suitable for use with Perspex® acrylic (except laminate cutters, guillotines and blanking dies)
For small jobs, Perspex® may be cut with fine-toothed hand saws such as fret saws and hack saws. The work must be securely fixed and only light pressure applied. Powered saws with blades having alternative teeth bevelled, as for aluminium, are particularly recommended for sawing Perspex® acrylic as are band saws and jigsaws.

Can I drill holes in Perspex® acrylic?
Standard woodworking twist drills can be used for all normal drilling work with Perspex®. Wherever possible, the work should be supported by a back stop made from either scrap Perspex® or hardwood to prevent splintering the exit hole. Under no circumstances should a centre punch be used before drilling Perspex®. A small pilot hole should be drilled first to locate the drill.

What is Solid Coloured Perspex® acrylic?
This means that the Perspex® acrylic colour does not allow transmission of light (eg if you held your hand up behind a solid colour sheet you would not see a shadow).
What is Translucent Coloured Perspex® acrylic?
This means that the although the Perspex® acrylic colour allows transmission of a minimal amount of light you are unable to see through the material (eg if you held your hand up behind a translucent colour sheet you would see a shadow, but you would not be able to see your hand). Translucent Perspex® acrylic is frequently used for light-boxes.
What is Transparent Coloured Perspex® acrylic?
This means that the Perspex® acrylic colour is see through. So in effect, the sheet is clear but tinted with a colour.
What is Silk Perspex® acrylic?
This means that the Perspex® acrylic has a frosted (anti-reflective) finish on one side of the sheet.
What is Frosted Perspex® acrylic?
This means that the Perspex® acrylic has a frosted (anti-reflective) finish on both sides of the sheet.
What is Fluorescent Perspex® acrylic?
This is a relatively new addition to the Perspex® acrylic range with an exciting fluorescent live edge, and is available in a range of colours.
The thickness of Perspex® acrylic coloured sheet I want is not listed, can you make it?
We can manufacture standard colours in any thickness - subject to a minimum order quantity of approx 16 full sheets.
I need to match a particular colour, can you help?
We can manufacture Perspex® acrylic to almost any custom colour imaginable - subject to a minimum order quantity of approx 16 full sheets.
What is the Thermal Expansion of Perspex® acrylic sheet?
Perspex® acrylic has a high thermal expansion coefficient compared to traditional glazing materials and allowance within the frames must be made in both directions for thermal expansion and contraction. Failure to observe this rule can lead to stresses in the sheet which can cause distortions in the panel and crazing at the edges of the sheet in time. An allowance of 5 mm per metre run length should be allowed in both dimensions during installation. This figure has been found from long experience to be sufficient for all locations and climates. For further details consult the Perspex® acrylic Design Guide
I want to protect a valuable painting, which Perspex® acrylic grade should I use?
Perspex® acrylic VA is a special UV grade acrylic sheet which has excellent ultraviolet absorbing properties to block damaging UV rays. This is a best-selling item to museums and art galleries.
I already have some Perspex® acrylic sheet, but it has a scratch on it - can you help?
Our Perspex® acrylic Polish allows you to simply polish out most minor surface scratches and imperfections from Perspex® acrylic and acrylic sheet
What are the dimensional tolerances on Perspex® acrylic sheet thicknesses?
Cast Perspex® acrylic is manufactured in accordance with ISO7823-1, which means for the thickness range of 2 to 25mm, a production tolerance of +/-10% plus 0.4mm (eg 8mm cast sheet could vary from 6.8mm to 9.2mm).Extruded Perspex® acrylic is manufactured in accordance with ISO7823-2, ie to a thickness tolerance of +/-10% for sheet thicknesses below 3mm and +/-5% for sheet thicknesses of 3mm and above.
Does Perspex® acrylic sheet have a fire rating?
How can I clean Perspex® acrylic sheeting?
The best method for cleaning Perspex® acrylic sheet is by washing with a solution of luke warm water with a drop of washing-up liquid, using a soft cloth to loosen any dirt and grime. Then, rinse with cold water and dry with a very soft cloth to prevent water spotting. You should not use chemicals, glass spray, or other abrasive cleaning materials, nor should you use any form of scraper or squeegee or other sharp instruments.
How is the light transmission of Perspex® acrylic calculated?
When light transmission values are given, they are for a nominal 3mm thickness. The light transmission of Perspex® acrylic varies according to thickness. Colour numbers with the letter "T" are constant transmission products. This means that the product has the same light transmission throughout the thickness range.
Is there a Perspex® acrylic colour which just transmits infra-red light?
Yes, Perspex® acrylic Black 962 will only transmit infra-red light.
How do I work out the weight of a Perspex® acrylic sheet?
By using the specific gravity of Perspex® acrylic sheet (1.19) you can use the following simple formula to work out the weight of any given sheet size:
Length (in metres) x Width (in metres) x Thickness (in mm) x 1.19 = Weight in kg
I'd like to make a Perspex® acrylic Splashback for my kitchen - is this possible?
Many of our customers have used our range of Perspex® acrylic colours to make modern splashbacks for kitchen areas. We can cut Perspex® acrylic sheets to almost any custom size - and we can also include cut-outs for sockets etc if required (we just need a drawing from you showing dimensions). To discuss your project in more detail, please contact us.Please note that Perspex® acrylic must not be positioned near to any naked flame (eg gas hobs), nor exposed to temperatures in excess of 75 degrees C.
Can I use Perspex® acrylic in my bathroom?
Perspex® acrylic can certainly be used in bathrooms. You can also use our range of adhesives and sealants to mount and seal around the edge of the Perspex® acrylic sheets to ensure a water-tight finish. Depending on your wall surface, you may need to pre-mount your Perspex® acrylic sheet to a board (eg MDF) prior to fixing to achieve a sound, flat finish.
