3M® Copper Conducting Tapes,
Code 1181 and 1182
Copper Foil with Conductive Adhesive - More Information
Product Description for Code 1181
3M 1181 Tape consists of a 1-ounce deadsoft copper foil backing and a unique electrically
conductive pressure-sensitive acrylic adhesive featuring the following:
- Deadsoft 1-ounce copper foil backing
- Conductive acrylic adhesive
- Supplied on a removable liner for easy handling and diecutting
Like other 3M shielding tapes, 3M 1181 is available in standard widths and as offered
by SPI Supplies but it is also available in other widths and lengths up to approximately
36 yards.

your custom requirements so that we can offer pricing.
Applications:
3M 1181 Tape is typically used for applications requiring excellent electrical conductivity
from the application substrate through the adhesive to the foil backing. Common uses
include grounding and EMI shielding in equipment, components, shielded rooms, etc.
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 a value 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).
Product Description for Code 1182
3M 1182 Tape consists of a 1-ounce deadsoft copper foil backing that is
coated both sides with and a unique electrically conductive pressure-
sensitive acrylic adhesive featuring the following:
- Deadsoft 1-ounce copper foil backing
- Conductive acrylic adhesive on both sides
- Supplied on a removable liner on both sides for easy handling and
diecutting
Like other 3M shielding tapes, 3M 1182 is available in standard widths and
as offered by SPI Supplies but it is also available in
other widths and lengths up to approximately 36 yards. Let us know your
custom requirements so that we can offer pricing.
Applications:
3M 1182 Tape is typically used to bond two surfaces together, both
electrically and physically. An example would be adhering a conductive
gasket to a conductive surface as part of an EMI shielding solution for
electronic enclosure.
Conductivity
Since 3M 1182 double sided copper tape would typically be used as an
electrical path between two surfaces, its most important feature is its
conductivity. Highly conductive particles in the acrylic adhesive provide a
multitude of electrical paths between the application substrate and the
surface of the copper foil on each side. The resistance of the conductive
path through the adhesive (measured over a 1 in² area) typically measures
only a few milliohms.
