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

This electrical tape is a thin copper-backed adhesive tape designed for electrical insulation and shielding tasks in industrial settings. It combines a conductive metal backing with an acrylic adhesive to provide a Compact solution for insulating joints, creating EMI barriers and performing minor repairs where space and temperature resilience are important.

• Copper backing provides EMI shielding and conductive continuity
• Acrylic adhesive delivers stable adhesion on varied substrates
• Operational range spans -40°C to +121°C for temperature resilience
• Thickness 0.045mm offers conformability in tight spaces
• Width 25mm suits narrow runs and precise application
• Length 10m supplies multiple repair and shielding operations

• Suitable for creating conductive seams in cable assemblies
• Ideal for localised EMI shielding on enclosures and panels
• Used for insulating and repairing electrical joints in control cabinets
• Can be used for bonding copper tabs and wrap-around shielding
• Used with automation equipment where heat resistance is required

The copper foil backing provides a low-impedance path for stray currents and electromagnetic fields, enabling effective local shielding and earthing when wrapped or bonded to conductive surfaces.

It will remain functional across a wide temperature span from -40°C up to +121°C, maintaining adhesion and dimensional stability within that range.

The acrylic-based adhesive is formulated to adhere reliably to metals, plastics and painted surfaces common in electrical and mechanical assemblies.

It conforms to RoHS requirements, indicating it is manufactured without specified restricted substances for compliant production contexts.
