3M 3M Black Copper Foil Electrical Tape, 25 mm x 10 m

This electrical tape is a thin copper-backed adhesive product designed for electrical and shielding tasks in industrial and electronics settings. It provides a conductive foil backing combined with an acrylic adhesive to support earthing and EMI mitigation while performing across a wide temperature range in automation, electrical and mechanical environments.

• Copper foil backing provides conductive path for shielding and earthing
• Acrylic adhesive ensures Durable adhesion on varied conductive surfaces
• Operates reliably to +121°C for high-temperature installations
• 0.025mm thickness allows conformity in tight or irregular gaps

• Suitable for EMI shielding and earthing of enclosures and cables
• Ideal for repairs on conductive surfaces in electronic assemblies
• Used with cable harnesses to enhance electrical continuity
• Can be used for moisture-resistant sealing in sensitive assemblies
• Used for spot shielding around connectors and PCB edges

The product uses a copper foil backing that delivers electrical conductivity for shielding and earthing tasks.

The acrylic-based adhesive offers strong initial tack and maintains adhesion on clean metal and composite conductive surfaces while resisting common environmental factors.

The foil-backed construction is 0.025mm thick, permitting close conformity to contours and minimal build-up when layered.

Yes, it retains functional performance at temperatures as low as -40°C, enabling use in cold environments and refrigerated equipment.
