EMI Shielding Tape With Adhesive
Series No. 2800
MAJR Products’ EMI shielding tape, also known as copper tape or foil tape, offers an economical EMI shielding solution for a variety of commercial uses. The tapes are available in copper or aluminum backed with conductive pressure-sensitive adhesives. Copper tape meets the requirements of MIL-T-47012 for corrosion resistance. Typical properties are shown in Table 1.
Copper tape is available with a non-conductive adhesive for applications requiring surface conductivity only. Both standard length rolls and die-cut custom shapes can be ordered. Other types of shielding tape are available upon request.
