Mesh Foil for window shielding 9000 - 9300 

Using Mesh foil is the easiest way to create transparent EMI/RFI-shielded windows.
You can shield existing standard displays, glass, acrylic, polycarbonate and PMMA windows yourself

What is Mesh foil?

Mesh foil is a very fine, electrically conductive wire mesh laminated between two layers of scratch-resistant transparent foil. The wires are so fine that they can hardly be seen with the naked eye. The product is very strong but it still bends easily.

It is easy to apply Mesh foil onto glass, acrylic and polycarbonate, either by hand or with a laminator. It can be supplied with or without self-adhesive.

The foil can be made with flying mesh on the sides or around the foil. This means that a part of the very fine wire mesh is not covered in transparent foil. The exposed edges of wire mesh can be used to create an electrical connection with your enclosure. Alternatively a conductive or non-conductive adhesive can be provided along the edges or there can be a silver busbar around the circumference.

Maximum sheet/roll width 1020 mm.

  • The wire mesh can be placed at a custom angle to prevent the moiré effect on your display (standard is 0 degrees).
  • A custom wire-mesh angle is only available with sheet styles 1 and 5

NOTE: For LCD displays, 17°, 35° or 45° are used typically. We recommend that you request a sample of the product to determine the proper angle of the wire mesh for your application.


Mesh foil with or without self-adhesive

  • Mesh foil is available with or without transparent self-adhesive.
    This is used to attach the Mesh foil to any existing window or display.

Standard available widths

We have mesh foil in standard widths of stock. The standard widths are 10, 20, 30, 40, 50, 100, 200, 250, 500 and 1000 mm. Any other width/size can be produced within days.

Turnkey windows

If you are interested in ready-made mesh-foil windows, please take a look at our 9700 series EMI/RFI shielded mesh-foil windows. Here the mesh foil is bonded between two layers of glass or plastic, or a single layer of mesh foil is fixed onto one side of a single glass or plastic window.


NEW Micro Suction Silicone adhesive

For easy manual application of the foil we have developed a new Micro Suction Silicone adhesive. This adhesive has a number of advantages that make the film easy to position. Our advise is to use standard adhesive only for laminating machines or very very experienced people. For all else use this new Micro Suction Silicone Adhesive

Benefits

  • Reusable / Repositionable
  • Never attach permanently
  • Easy to apply by hand, less bubbly

Please note : Mesh foil with Micro Suction Silicone adhesive has a thickness of 450 micron / 0.45 mm.


Please note: the top layer can be affected by acids, for example from human skin. To protect the conductive layer, you can apply a transparent film or you can have the adhesive side facing out. Max. working temperature 60 ºC.

Small optical defects are expected to occur with this product. If you require a product that has absolutely no optical defects, please contact us for the "superior selected quality". Do please realize that due to the extreme care needed to manufacture these products, they can be several times more expensive.
