Clear extruded acrylic sheet is a high quality acrylic sheet material with a light transmission level higher than that of all other thermoplastic sheet materials except cast acrylic sheet. Extruded acrylic is of a slightly lower quality than cast acrylic but its production process is more economical making it a lower cost material to purchase.

Key features

  • Excellent thickness tolerance
  • Optical clarity
  • High gloss surface on both sides
  • Hard wearing
  • Weather resistant
  • Easy to bend and shape
  • Economical
  • Suitable for vacuum forming

Typical applications

  • Point of sale
  • Retail display
  • Models
  • Display cases
  • Glazing

Detailed description

Excellent thickness tolerance

Extruded acrylic has an excelent thickness tolerance meaning there is little variation in thicknesses within the same sheet of material, thiis is also true of the thickness tolerance between multiple sheets of material. The thickness tolerance of extruded acrylic sheet is +/- 5% while the thickness tolerance of cast acrylic sheet cab be as high as +/- 15%.

Optical clarity

While not quite as high as the optocal clarity of clear cast acrylic sheet, clear extruded sheet still performs very well in this area. The economic cost of extruded acrylic is often required for high volume projects, so unless the highest possible levels of optical clarity are required, then extruded acrylic is an attractive option.

High gloss surface

Clear extruded sheet has a high gloss finish on both sides.

Weather resistant

With excellent resistance to the elements, clear extruded acrylic sheet performs very well outside. No significant changes in appearance are expected over 10 years.

Fabrication

Extruded acrylic sheet is very easy to work with.

Vacuum forming

Extruded acrylic is suitable for vacuum forming making it a popular choice when complex shapes are required.  

Production process

Clear extruded acrylic sheet and clear cast acrylic sheet are visually very similar but are two different materials each with advantages and disadvantages and each produced by very different manufacturing processes. Extruded clear acrylic sheet is produced by an extrusion process, acrylic resin pellets are heated to a molten mass which is continuously pushed through a die, the position of which determines the thickness of the sheet produced. Once through the die, the molten mass looses temperature and can be trimmed and cut to the required sheet sizes. The continuos nature of the extruded acrylic production process produces larger batches than that of cast acrylic production making it a more economical material.

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®.

What is the difference between cast acrylic and extruded acrylic?

Acrylic is manufactured in two versions - cast and extruded. Cast acrylic is made by pouring the hot liquid acrylic ingredients between two sheets of glass which are separated by rubber gaskets - the thickness of the gasket determines the thickness of the acrylic sheet being made. The sealed glass plates are placed into an oven and allowed to heat during which the chemical processes and changes take place. Finally, the sheets are allowed to cool. Cast acrylic is commonly used for glazing, signage and retail displays. Extruded acrylic is made by pouring hot liquid acrylic ingredients into a form or die before the acrylic is forced through rollers which leaves the material with an even thickness and finish. Cast acrylic is generally regarded as a better quality material and offers a number of advantages over the extruded variant such as being more resistant to chemicals and solvents, less prone to scratching, easier to machine and fabricate and available in a far wider range of colours and surface finishes i.e. gloss/matte. Extruded acrylic is commonly used for lighting applications, interior decoration and screening.

Why is Clear Extruded acrylic cheaper than Clear Cast acrylic?

Cast acrylic is generally regarded as a better quality material and offers a number of advantages over the extruded variant such as having a higher optical clarity and superior surface finish, being more resistant to chemicals and solvents, less prone to scratching, easier to machine and fabricate and available in a far wider range of colours and surface finishes i.e. gloss/matte. The manufacturing process for cast acrylic is longer and more complex than that of extruded acrylic which in-turn generally makes extruded acrylic slightly cheaper.

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
  • Signage
  • Laser cutting (edge finish marginally better on extruded, however Cast does not produce burrs)
  • Laser engraving
  • Cutting i.e. sawing and routing
  • Furniture and interior design
  • Shopfitting
  • Exhibitions
  • POS displays
  • Aquariums
  • Museum Quality Glazing
  • Lighting
  • Cosmetic displays
  • Thermoforming (bending, forming, blowing, vacuum forming)
  • Glazing (greenhouse & sheds)
  • Boxes & Display Cases
  • Replacement Picture Framing Glass (note, UV protective acrylic only available in Cast)

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.

Required clear acrylic circular tops for small coffee tables, cut to exact size, this was done with precision and fitted perfectly. Would definitely buy from again from them. Much cheaper and safer than glass alternatives.
