3M 3M Black Copper Foil Electrical Tape, 100mm x 10 m

This electrical tape provides a conductive foil solution for industrial and electronic environments, combining a metal backing with an acrylic adhesive for electrical shielding and insulation tasks. It is intended for use where a thin copper layer is required to manage EMI/RFI and create conductive paths while remaining compatible with automated assembly and manual fitting in workshops and production lines.

• Copper backing ensures conductive shielding and continuity
• Acrylic adhesive offers stable adhesion across varying substrates
• Operates from -40°C to +121°C for extreme-temperature use
• Thin 0.025mm profile minimises bulk while retaining conductivity

• Suitable for EMI/RFI shielding in electronic enclosures
• Ideal for creating earthing strips on chassis
• Used for repair or modification of sensor and control wiring
• Can be used for tape seams in high-temperature assemblies
• Used with automation fixtures requiring wide conductive tape

The tape is supplied in a 100mm width to cover broader seams and reduce joint counts on shielding surfaces.

Rolls are available in 10m length to support multiple assembly or maintenance tasks without frequent changeover.

A copper foil backing is paired with an acrylic adhesive to preserve electrical continuity while adhering to different substrates.

It remains dimensionally functional between -40°C and +121°C, suitable for environments with significant thermal variation.
