3M 1181 COPPER TAPE - 1 IN WIDTH X 18 YD LENGTH - 2.6 MIL TOTAL THICKNESS – 27468

The 3M 1181 Copper Foil Shielding Tape (1 in × 18 yd, 2.6 mil total thickness) is a high-performance conductive tape engineered for efficient EMI/RFI shielding, grounding, and static discharge control in aerospace and electronic systems. It features a dead-soft copper foil backing and a pressure-sensitive conductive acrylic adhesive that ensure low contact resistance, consistent conductivity, and excellent conformability over irregular or curved surfaces. Its solderable surface resists oxidation and maintains reliable performance in harsh environments exposed to temperature variations, vibration, and electromagnetic interference. Ideal for aerospace applications such as avionics bay shielding, cable harness grounding, and composite bonding, this tape provides stable electrical continuity and long-term durability under demanding operational conditions.
