PERSPEX®  / Altuglas® / Oroglas®



We are all guilty of it, every vacuum cleaner is a “Hoover®” and every piece of clear plastic is “Perspex® ”. Perspex® was the trademark, branding, used by ICI for their range of acrylic (PMMA) sheets. The Perspex® brand of acrylic is now manufactured by the Lucite International Ltd group of companies.


Engineering & Design Plastics Ltd mainly stock and distribute the Perspex® brand of cast acrylic sheet but we also can supply Altuglas® and Oroglas® cast acrylic sheet which are alternative brands of acrylic sheet. In the past, we have also supplied REPSOL GLASS® cast acrylic sheet which was manufactured by Repsol YPF. In  March 2008 Altuglas International purchased the acrylic production facilities of Repsol YPF. The REPSOL GLASS® brand has now been phased out and sheet manufactured at the former Repsol YPF plant is now been branded Oroglas®. Engineering & Design Plastics Ltd can also supply other brands of acrylic sheet, to order, if you need another specific brand of acrylic, for instance Irpen Policril®, Madreperla Setacryl® or ROEHM Plexiglas® we would like the opportunity to try and help you with your requirement.

Acrylic sheet is manufactured in two forms; cell cast and extruded sheet. Cell cast acrylic sheet is available in a wide range of thicknesses and colours, including blocks, colours and a limited range of surface patterns.

Extruded acrylic is available as clear sheet and in a limited range of opal and tinted colours and impact modified grades although minimum orders can apply. Extruded acrylic sheet has a good surface finish and consistent properties, which make it suitable for many internal and external glazing applications. Extruded acrylic sheet usually has a tighter tolerance on the thickness than that of standard cast acrylic sheet which is surprisingly wide (see tables below). Extruded acrylic sheet can be solvent bonded to its self, however we would always recommend where possible using a cast acrylic when bonding. The extruded material has more internal stresses in it due to the manufacturing process. It is more susceptible to crazing due to the solvents in the glue than the cast product. It is always good practice to vent any fumes away from the product when bonding, even when using cast material.

Please note that the solvent adhesives are only available for collection from our Cambridge sales office or local delivery on our own vehicles. We can send this goods nationally or internationally by carriers.

We would like draw your attention to the tolerance on the thickness of cast acrylic sheet. It is a lot wider than many people expect! For example a nominal 6mm thick Perspex® sheet can actually measure as thin as 5mm or as thick as 7mm. This problem is compounded by the fact that the same sheet might be on top tolerance in one position and bottom in another.


Perspex® Cast sheet

Standard sheet size











































Acrylic sheet, block, rod and tube have properties which are suitable for a wide variety of applications ranging from precision engineering components to domestic and commercial products. They are easy to machine / work with (we would recommend the cast product for complicated machined components due again to the inherent stress in the extruded product) using conventional equipment and can be thermoformed by inexpensive apparatus.

  • Half the weight of glass
  • Outstanding transparency
  • Good flexural strength
  • Outstanding in all climates.
  • Will not noticeably yellow in less than 10 years. See Perspex warranty below
  • Good resistance to many common chemicals
  • Good resistance to breakage 7 to 10 times stronger than standard glass of same thickness.
  • Cracks rather than shatter into multiple fragments.

It is easily worked using conventional tools and machines and can be bonded to itself and other materials. The strength and durability of acrylic make it an ideal material for static and working models alike and its outstanding clarity ensures that the innermost parts of the most complex of these are easily seen.

  • Building
  Because of its light weight, high strength, superb clarity, surface finish and the ease with which complex shapes can be formed, acrylic is widely used in the building industry for secondary flat glazing and roof lights, balcony guards, screens, light fittings and countless similar applications.

Engineering & Design Plastics Ltd stock two very basic and cost effective double glazing systems, EASYFIX and EASYGLAZE which are glazed with 2mm thick panels. The majority of our customers use clear extruded acrylic sheet. Go to




  • Museums & Galleries

Countless valuable exhibits and priceless works of art are protected on display throughout the world by acrylic showcases. Excellent viewing is assured because of the exceptional clarity of acrylic and its high transmission of 92%. Frames are rarely required as acrylic may be readily cemented together to form very strong but lightweight units to guard against theft and damage.
