Foil EMI Shielding Tape 1181 Copper 3M with Conductive Adhesive, 0.066mm Thick Waterproof Acrylic No Printing Carton Sealing

• Full Description:

3M 1181 Tape consists of a 1-ounce deadsoft copper foil backing and a unique electrically conductive pressure-sensitive acrylic adhesive.

1. Deadsoft 1-ounce copper foil backing


2. Conductive acrylic adhesive


3. Supplied on a removable liner for easy handling and diecutting

Like all 3M shielding tapes, 3M 1181 is available in standard and  custom widths and lengths. Standard length is 18 yards.

• Applications:

1. 3M 1181Tape is typically used for applications requiring excellent electrical conductivity from the application substrate through the  adhesive to the foil backing.


2. Common uses include grounding and EMI shielding in equipment, components, shielded rooms, etc.


3. Required by reliable point-to-point electrical contact, particularly EMI shielding, grounding and static charge draining.


4. The copper foil backing is solderable and resists oxidation and discoloration.

• Shielding Effectiveness:

Many factors determine the true shielding effectiveness of a  shielding tape, including type and thickness of foil, adhesive type, intimacy of contact, smoothness of application surface, strength and  frequency of the EMI signal, etc. However, using standard tests and fixtures, it is possible to determine avalue for the attenuation.For 3M 1181 Tape, typical shielding effectiveness (far field) is in  the range of 60dB to 80dB (30 MHz to 1 GHz).
