What can I use Perspex for?
Perspex is extremely versatile and can be used in applications as diverse as signs, POS, visual communication, window glazing, acoustics, design, architecture, furniture, perspex boat and car windows, kitchen and bathroom splashbacks - the list is almost endless.
 [back to FAQs]

What are the advantages of using Perspex sheet?
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
 [back to FAQs]

How is Perspex made?
Cast Perspex 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 sheet is produced from the acrylic polymer Lucite Diakon in the form of granules, and extruded into sheet.
 [back to FAQs]

What is Solid Coloured Perspex?
This means that the Perspex 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).
 [back to FAQs]

What is Translucent Coloured Perspex?
This means that the although the Perspex 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). This type of material is frequently used for light-boxes.
 [back to FAQs]

What is Transparent Coloured Perspex?
This means that the Perspex colour is see through. So in effect, the sheet is clear but tinted with a colour.
 [back to FAQs]

What is Silk Perspex?
This means that the Perspex has a frosted (anti-reflective) finish on one side of the sheet.
 [back to FAQs]

What is Frosted Perspex?
This means that the Perspex has a frosted (anti-reflective) finish on both sides of the sheet.
 [back to FAQs]

What is Fluorescent Perspex?
This is a relatively new product with an exciting fluorescent live edge, and is available in five colours. Sheets are also available with a frosted finish which forces an even brighter fluorescent live edge.
 [back to FAQs]

I'd really like a sample of a particular Perspex colour - is that possible?
You can order samples of Perspex at our sister site www.theplasticshop.co.uk

Is there a grade of Perspex that can actually block UV light?
Perspex VA is a special UV grade acrylic sheet which has very good ultraviolet filtering properties to block damaging UV rays. Click here for more info about Perspex VA
 [back to FAQs]

What are the dimensional tolerances on Perspex sheet thicknesses?
Cast Perspex 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 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.
 [back to FAQs]

Does Perspex sheet have a fire rating?
Perspex achieves a UK Class 3 fire rating.
 [back to FAQs]

How is the light transmission of Perspex calculated?
When light transmission values are given, they are for a nominal 3mm thickness. The light transmission of Perspex 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.
 [back to FAQs]

Is there a Perspex colour which just transmits infra-red light?
Perspex Black 962 will only transmit infra-red light.
 [back to FAQs]

How can I clean Perspex sheeting?
Perspex sheet can be cleaned 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.
 [back to FAQs]

How do I work out the weight of a Perspex sheet?
By using the specific gravity of Perspex sheet (1.19) you can use the following simple formula to work out the weight of any Perspex sheet or cut to size panel:
Length (in metres) x Width (in metres) x Thickness (in mm) x 1.19 = Weight in kg
