Conductive tapes for EMI shielding. These materials are used to shield plastic housings, cables, and enclosures against undesirable electromagnetic signals. The tapes are also used to close seams in electrical enclosures and Faraday cages.
Many EMI problems can be solved easily by the use of conductive tape. Some of the most commonly used materials are Mu-copper foil, reinforced Amucor foil and highly conductive textile.
All of these materials are available with or without (conductive) self-adhesive and an optional insulation layer.
In addition, all tapes can be cut according to the customer's CAD drawing into any desired shape, width and length.

EMI-shielding tapes (Select one of the types of tape below to continue)
Mu-copper tape has superb shielding performance (also at low frequencies), can be soldered, and is easy to fold into the desired shape.
Reinforced Amucor tape is both cost-effective and heat resistant. This thin foil tape can be applied easily to any surface or housing shape.
4711 - 4715
Conductive textile tape with self- adhesive can be applied easily to plastic housings to cover complex forms and shapes.
Aluminium tape was developed espacially for EMI/RFI-shielding/screening in aluminium housings and frames to prevent galvanic corrosion.
3204 & 3304
A metal tape with a highly conductive or standard self-adhesive on one side and masking tape on the other side. This tape is used when a contact surface is needed after a metal case has been coated.
