CHO-FAB
nickel-plated cloth coated with Chomerics’
highly conductive pressure-sensitive
adhesive. This adhesive contains a
uniform dispersion of conductive particles
that create a very low electrical resistance
through the tape. This feature results in
superior shielding performance in a wide
variety of environmental conditions.
strong, lightweight and has excellent
conformability/wrapability to enhance
shielding performance and appearance.
Use of corrosion resistant nickel-plated
cloth and Chomerics’ superior metal-
particle-filled conductive adhesive
technology produces a tape used in a
wide variety of EMI shielding and ground-
ing applications.
EMI shielding solution for a variety of
commercial uses. The tapes are available
in copper, aluminum, or tinned copper foil
backed with Chomerics’ highly conductive
pressure-sensitive adhesive. The copper
version of CHO-FOIL tape meets the
requirements of MIL-T-47012 and the
tinned copper foil tape meets MIL-T-10727
for corrosion resistance.
tapes are available in standard 36 yard
length rolls, and die cut custom configura-
tions. * For applications requiring surface
conductivity only, copper tape is available
with a non-conductive adhesive.
