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
  • 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.

I have used Simply Plastics a couple of times. I think the prices, range of products (and colours), communication, delivery etc are just great and I look forward to finding new reasons for ordering colourful bits of plastics etc from SP. A good find! Thx.
