Conductive Foil Tape for Shielding

3M 1120 is a single-sided aluminum foil tape with an acrylic adhesive and a release liner. It serves electrical shielding and grounding tasks in HVAC and general industrial environments. The roll provides 6 yards of continuous material. The silver finish identifies the foil backing at a glance.

Temperature and Voltage Boundaries

The tape operates reliably from -40 °F up to 265 °F and carries a 600 V rating. These limits define the practical envelope for any joint, splice or wrap you seal with it. Shielding effectiveness is specified at 69 dB. Exceeding either the thermal or voltage boundary degrades both adhesion and electrical performance.

Shielding Effectiveness Is the Deciding Spec

At 69 dB the tape meets many EMI/RFI attenuation requirements for foil-based shielding. If your design demands higher attenuation, a different construction will be necessary. Buyers who need greater shielding performance should select an alternative product. The 4 mil thickness and acrylic adhesive support standard termination methods.

Questions about this item

Should I choose the 6-yard roll or a different length for my shielding job?

The 6-yard continuous roll provides enough foil-backed length for most cable-wrap and duct-sealing tasks without needing multiple splices.

What does the 69 dB shielding figure mean once the tape is applied?

At 69 dB the foil backing blocks the vast majority of electromagnetic interference across the rated frequency range when wrapped with proper overlap.

How does the 600 V rating limit the way I can use this tape?

The 600 V rating caps the maximum circuit voltage the acrylic adhesive and foil can safely insulate, so it suits low-voltage control wiring but not mains power above that level.
