Aluminiumfolie afschermband 3M 16,5 m × 12 mm, zilver

3M aluminium foil shielding tape, 16.5 m × 12 mm in silver, provides a narrow conductive layer intended for EMI/RFI shielding, grounding, splicing and sealing joints on cables and conductive surfaces. The tape combines a thin aluminium foil carrier with a pressure-sensitive conductive adhesive to maintain electrical continuity across seams and overlaps while conforming to curved or irregular surfaces common in electronics assembly, repair and HVAC applications.

Advantages

This aluminium foil shielding tape offers a reliable conductive surface for mitigation of electromagnetic and radio-frequency interference and for establishing low-resistance paths to ground. Its narrow width and flexible foil allow precise placement in tight or confined spaces and along cable runs. The pressure-sensitive adhesive bonds quickly and holds on metal, foil-faced insulation, cable jackets and many other conductive or semi-conductive substrates, providing durable sealing against dust and moisture in joints.

Suitable for

• EMI/RFI shielding in electronic assemblies and repair work
• Grounding and continuity restoration on cable splices
• Sealing and patching seams in HVAC ducts and foil-faced insulation
• Taping narrow or hard-to-reach areas where conductive tape is required

Key specifications

• Length: 16.5 metres
• Width: 12 millimetres
• Color/finish: silver aluminium foil
• Construction: aluminium foil carrier with conductive pressure-sensitive adhesive
• Typical properties: conformable to curved surfaces, conductive adhesive for electrical continuity

How to use

Clean and dry the application surface to remove oil, dust and loose particles for optimal adhesion. Unwind the required length of tape and press it firmly onto the surface, smoothing from the center outward to remove air pockets. Overlap adjacent tape runs or wraps to ensure continuous conductive contact across seams. For grounding applications, ensure secure mechanical contact to a verified ground point or use an appropriate conductive fastener where necessary.

Recommendations

Store the tape in a cool, dry location away from direct sunlight. For long-term installations, verify adhesive compatibility with the substrate and test a small area if surface coatings or plasticizers are present. Use personal protective equipment when working with sharp edges or metal surfaces. Not intended as primary electrical insulation; follow applicable electrical safety standards when performing grounding or shielding work.
