1267 Tape
Embossed Aluminum Foil
Data Sheet
Product Description
3M ? 1267 Tape consists of an embossed 1-
ounce deadsoft aluminum foil backing and an
aggressive pressure-sensitive acrylic adhesive.
The edges of the embossed pattern pressed
into the foil cut through the adhesive layer to
establish reliable metal-to-metal contact
between the backing and the application
Applications
3M 1267 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.
substrate.
Shielding Effectiveness
? Embossed deadsoft 1-ounce aluminum foil
backing
? Conductivity “through the adhesive”
? Supplied on a removable liner for easy
handling and diecutting
Like all 3M shielding tapes, 3M 1267 is
available in standard and custom widths and
lengths. Standard length is 18 yards.
? Widths from 1/4” to 23”
? Longer lengths up to several times normal
length, dependent upon width. Check with
Customer Service.
Properties
Backing thickness
Total thickness (backing plus adhesive)
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 1267 Tape, typical shielding
effectiveness (far field) is in the range of 55dB
to 80dB (30 MHz to 1 GHz).

Footnote: 1. Test method ASTM D 1000
2. MIL-STD-202 Method 307 maintained at 5 psi (3,4 N/cm 2 ) measured over 1 in 2 surface area. The edges of the
embossing pattern in the foil backing penetrate through the nonconductive adhesive to make metal-to-metal contact
with the application substrate.
3. UL-recognized for flame retardancy per UL 510, Product Category 0ANZ2, File E17385.
