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

This electrical tape provides a conductive copper-foil backed solution for shielding and insulation tasks within industrial and electronic environments. It combines a thin metallic backing with an acrylic-based adhesive to offer a Compact roll intended for use where both electrical continuity and surface conformity are required.

• Copper foil backing offers effective electromagnetic shielding
• Acrylic adhesive maintains bond across a wide temperature range
• Operates continuously up to +121°C for high-temperature tasks
• Remains functional down to -40°C for cold environment use
• Very thin 0.025 mm foil enhances conformability to contours

• Suitable for PCB-level electromagnetic shielding and earthing
• Ideal for cable wrap and splice shielding in control panels
• Used for tray and enclosure lining to reduce interference
• Can be used for repair and retrofit of shielding in instrumentation
• Used with sensor housings to maintain EMC performance

The product uses a copper-foil backing paired with an acrylic adhesive to balance conductivity with secure adhesion.

Each roll supplies 10 m of tape with a 25 mm working width for precise application.

The foil thickness is 0.025 mm which improves flexibility and enables tight conformity around small components.
