Detailed description
Light transmission
Acrylic cast sheet has a light transmission of 37%. The opal acrylic diffracts and diffuses light evenly making it the perfect choice for illuminated signage.
Hard wearing
Cast acrylic is one of the hardest thermoplastic sheet materials available and its attractive aesthetics remain for longer than other plastic sheet materials.
Light weight
Opal cast acrylic weighs half as much as an equivalent glass panel making fabrication, installation and transportation a far more attractive proposition.
High gloss finish and easy to clean
Its high gloss finish is not only very attractive but also more practically very easy to clean.
Weather resistant
With excellent resistance to the elements, cast acrylic performs well outside. No significant changes in appearance are expected over 10 years.
Manufacturing process
Cast acrylic is manufactured by pouring monomer between two sheets of high quality glass and polymerised in batches in a carefully controlled manufacturing process.
Recyclable
Opal cast acrylic can be recycled all the way back to its original raw material, the monomer.

We provide a fast delivery service throughout the UK using recognised Couriers such as Royal Mail, DHL, and Parcel Force.
Delivery prices are calculated based on the length of the longest side of the material ordered i.e. the delivery price of a panel measuring 1500mm x 1000mm would be based on the 1500mm dimension. Only one delivery charge is charged per order regardless of how many items are ordered.

Third-Party Deliveries
Some products are dispatched directly from the manufacturer and delivered by a third-party courier. If applicable, this is clearly stated on each Product page under the 'Delivery' tab/section.
Can I collect my order from Simply Plastics?
Yes, of course. Orders can be collected from our premises in Colchester, Essex. At the final stage of the checkout process there is a delivery option labelled "Collection/pickup" which is free. Once your order is complete, you will be notified by email along with our address and collection times.
I need my order urgently, can I pay for faster shipping?
Yes. We offer an express delivery service which aims to deliver all orders in 1-3 working days. Orders are delivered by a recognised courier company and may require a signature on delivery.
What are polished edges?
When we cut an acrylic sheet to size, the saw blade/router toolbit produces a matte finish on the edges of the panel. We use a technique called diamond polishing to polish the edges to a bright, smooth and glossy finish.
Our diamond edge-polishing machine polishes the edge of acrylic by running a rotating, diamond tipped wheel along the edge of the material.
You can read more about the techniques used to polish Perspex® in our blog post, The Ultimate Guide to Polishing Perspex®.
Whats the difference between Plexiglass and Plexiglas®?
These two terms are pronounced the same and spelt almost identically, however, Plexiglass is the genericized trademark or proprietary emponym that has become synonymous with acrylic sheeting in most of Europe and North America whereas Plexiglas® is the brand name for acrylic sheets manufactured by Röhm GmbH in Germany. Whilst Plexiglass has become the generic trademark for acrylic sheets in Europe and North America, the brand name Perspex® is synonymous with acrylic sheeting in the UK.
Whats the difference between Plexiglas® and Perspex®?
Both Plexiglas® (most commonly spelt Plexiglass) and Perspex® are brand names of Acrylic sheet. Röhm GmbH, based in Germany, are the manufacturers of Plexiglas® whereas Perspex® is manufactured in the UK by Perspex International Limited. Both manufacturers supply a wide range of colours and thicknesses. Whilst the brand names Plexiglas® and Perspex® are different, ultimately the acrylic sheet that they manufacture is the same albeit each manufacturer might tweek the formulation to increase or enhance UV-resistance, light transmission or colour.
Which applications are best suited to Cast or Extruded Acrylic?
When deciding whether Cast Acrylic or Extruded Acrylic is best for your project it’s worth considering the specific application and desired finish you hope to achieve. The table below provides some examples of the most suitable type of acrylic sheet to use for specific applications.
| Cast Acrylic | Extruded Acrylic | |
| Application |
|
|
In our experience, whilst some projects/applications will require specific characteristics of either Cast or Extruded Acrylic, in most cases the choice can be made based on either colour, thickness or cost, as below:
- Clear or Colour: Extruded acrylic is generally only manufactured in clear, black and white and therefore if there is a requirement for any other colour, Cast Acrylic is the only choice.
- Thickness: Cast acrylic is commonly manufactured in thicknesses up to 100mm whereas extruded is generally available in a maximum thickness of 20mm (Simply Plastics stock up to 50mm in Cast and 10mm in Extruded).
- Cost: Extruded is marginally cheaper and therefore any requirement for a large quantity of sheets/panels, where the benefits of cast acrylic are not important, is likely to be more cost effective produced in Extruded acrylic.
How can I calculate the weight of a Perspex Panel?
All of the different types of plastics that are available on our website, whether they be a panel, a disc, tube or rod, show the weight of the piece you require once you have entered your dimensions, shown in grams or kg.
The weight of any plastic can be calculated using the simple formula: Weight = Volume x Density
Read our blog post on how to calculate the weight of a variety of different plastics covering panels, discs, road and tube.
