Amucor foil and tape 4700

Amucor foil and tape for EMI shielding. Amucor foil or tape can be used to shield plastic housings and enclosures.

Many EMI problems can be solved easily by the use of Amucor foil or tape, a commonly used material. Amucor foil and tape can be produced with or without (conductive) self-adhesive and an optional insulation layer.

Amucor tape can be cut to any width starting at 3 mm and can be delivered from stock. The most commonly used width is 25 mm; the standard roll length is 16.5 meters.

If coverage of large surfaces is needed, it is usually best to use tape with a conductive self-adhesive in combination with foil. This solution is much cheaper than only using tape.

Amucor foil can also be delivered as die-cut, according to the customer's drawing, on a strip or in pieces (stickers), with optional self-adhesive.

Amucor foil (4701)

The reinforced Amucor foil is both cost-effective and heat resistant. This thin foil can be applied easily to any surface and any shape of the housing. We can also supply the foil, which is 0.04 mm thick, in a die-cut version.

  • Cost-effective
  • Easily follows the contours of the housing
  • Fire-retardant
  • Extremely strong
  • Corrosion-free

Amucor tape with standard adhesive (4702)

This is an Amucor tape (a type of aluminum) that is 11 microns thick, reinforced with polyester (23 microns thick), and with an acrylic adhesive on the back.

Amucor foil with PET in the middle (4716)

Amucor foil + PET film + Amucor foil. This product consists of two layers of 11-micron thick Amucor (a type of aluminum) with a 23-micron layer of polyester in between. This material is extremely strong.

Amucor foil with a reinforcement net (4706)

Amucor foil can also be produced with a strengthening reinforcement net. Because the reinforcement net makes this material so strong, it can be produced in a very large width of 3100 mm. This material is designed to cover walls and floors for protection against unwanted radio frequencies (RF). The material can also be used to quickly create a shielded room, for example by covering the walls of a wooden box. Please note: at the top of the metal is a thin insulation layer for protection against corrosion.

Amucor foil with a reinforcement net can be produced as a foil (4706) without self-adhesive but is also available as tape (4707), with standard adhesive.

Shielding performance

In the table below you will find the shielding characteristics of Amucor foil.

Many factors influence the actual effectiveness of an EMI/RFI-shielding tape after it has been applied, such as type and thickness of the foil, type of adhesive, closeness of contact, smoothness of the application surface, strength, and frequency of the EMI/RFI signal, etc. Still, a nominal attenuation value can be determined using standard tests and fixtures.

For Amucor tape, typical shielding effectiveness (far field) is in the range of 60 dB to 80 dB (10 kHz to 20 GHz).
For more specifications see the table and graph below.

Field Frequency Amucor foil
    0.04 mm thick
E 1 MHz 121 dB
E 10 MHz 110 dB
E 100 MHz 103 dB
E 400 MHz 98 dB
P 1 GHz 92 dB
P 10 GHz 85 dB
