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

This electrical tape provides a conductive backing for shielding and insulation tasks in demanding industrial environments. It combines a metallic foil substrate with an acrylic adhesive to offer a versatile solution for electrical continuity and surface protection across a wide temperature range. The product is intended for professional use in electronics, electrical and mechanical settings where compact, conformable foil tape is required.

• Copper-backed foil offers EMI shielding and continuity
• Acrylic adhesive maintains tack at low temperatures
• Operates to +121°C for high-temperature applications
• Withstands down to -40°C for cold-environment performance
• Thin 0.045mm profile for tight conformability

• Suitable for EMI/RFI shielding on assemblies and enclosures
• Ideal for earthing straps and conductive repairs
• Used for insulation and protection in switchgear and panels
• Can be used for bonding copper foil to irregular surfaces
• Suitable for industrial maintenance where heat resistance is needed

The acrylic adhesive provides Durable adhesion to metallic substrates while remaining flexible for hand or tool application.

The roll is supplied as a 100mm width and a 10m length enabling coverage estimates and minimal overlap for shielding seams.

With a thickness of 0.045mm the foil conforms closely to contours, allowing neat application around edges and tight radii.

Its rated maximum operating temperature of +121°C supports continued use in high-temperature zones common in power and industrial equipment.
