Like all 3M shielding tapes, 3m 1181 is available in standard and custom widths and lengths. 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.

Applications:

3M 1811 tape is typically used for applications requiring excellent elecrical 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 poosible 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).
