9900 Transparent foil

Transparent EMI/RFI-shielding foil

Transparent shielding foil with speciality of one side conductive meanwhile optical transmittance, is widely used for applications of EL panel, LCD EMI shielding, touch screeen, 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 eletromagnetic 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.

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, standard adhesive only for laminating machines or very very experienced people else use this new Micro Suction Silicone Adhesive

Benefits

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

Please note : Transparent shielding foil with Micro Suction Silicone adhesive has a thickness of 370 micron / 0.37 mm.


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

Small optical defects are allowed in this product. If you require a foil that is absolutely free from optical defects, feel free to contact us for the "superior selected quality". Please realize that due to the extreme caution needed to manufacture these products, they can be several times more expensive.
