Transparent EMI/RFI-shielding foil 9900

A polyester film with a layer of transparent conductive coating. This offers excellent electrical and electromagnetic shielding.

Description

Transparent shielding foil with specialty of one side conductive meanwhile optical transmittance, is widely used for applications of EL panel, LCD EMI shielding, touch screen, flexible solar cell etc.

Transparent EMI/RFI-shielding foil 9900 series is a polyester film with a transparent conductive coating. The foil provides excellent electric and electromagnetic shielding of 40 -70 dB at 10 kHz to 300 Mhz and 25-40 dB from 300 MHz to 22 Ghz.

In addition to EMI/RFI/EMC shielding it is also used
for grounding and static discharge applications.
Typical applications are transparent shielding panels
for visual displays in instrumentation equipment, control panels and computers. The light transmission is 65-95%, depending on the electrical conductivity (20-5 Ohm/sq).

Due to its transparency, Transparent EMI/RFI-shielding foil 9900 series is the optimal choice for optical clarity.

For TEMPEST sites or radar/telecom protection, large dimensions are available.

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
  • Easily applied by hand, less bubbling

Please note: Transparent protective foil containing Micro Absorbent Silicone adhesive has a thickness of 370 microns / 0.37 mm.


Please note: the top layer can be affected by acid, for example from the human skin. To protect the conductive layer, you can apply a transparent film or use the non-conductive side on top.

Small optical defects are allowed in this product. If you need a product that is absolutely free from optical defects, please contact us for the “superior selected quality”. Do be aware though that due to the extreme caution required to manufacture these products, they can be several times more expensive.
