3M Metallic Tape, 19mm Width, 0.17mm Thickness - 7000029006


This metallic tape provides a conductive, lead-backed solution for EMI/RFI shielding and earthing tasks in industrial settings. It is suited to electrical and electronic assemblies where conductive continuity and surface coverage are required, offering a thin metallic layer for contact and mitigation of electromagnetic interference across a range of ambient conditions.

Features and Benefits:


• High adhesion rated at 490 N/cm provides secure bonding under stress
• Conductive rubber adhesive ensures electrical continuity where applied
• Lead backing delivers effective shielding for interference control
• Tensile strength of 350N/100mm resists mechanical strain during installation
• Operates between -51°C and +107°C for wide temperature resilience
• Thickness 0.17mm supports low-profile conformable applications

Applications


• Suitable for EMI/RFI shielding on enclosures and chassis
• Ideal for earthing straps and conductor repair on assemblies
• Used for seam and joint bonding in cable management systems
• Can be used for contact restoration on shielding surfaces
• Used with sensor housings to maintain conductive continuity

How should it be applied to ensure best electrical contact?


Surfaces should be clean and degreased before application

firm pressure aids the rubber adhesive to conform and make low-resistance contact with the substrate.

What handling precautions are needed for the backing material?


Standard lead-handling hygiene is recommended, including minimising dust and washing hands after use

avoid creating fine particulates during cutting.

How long is a typical roll and what width is supplied?


Each roll provides 32.9 m of tape supplied at a width of 19mm for extended runs without frequent splicing.

What mechanical limits should installers consider?


The tape’s tensile capacity of 350 N/100mm indicates good resistance to pull forces but users should avoid prolonged flexing that could fatigue the backing.

Which standard relates to its specification?


The tape conforms to the HH-T-29B standard, reflecting its intended performance characteristics for conductive shielding materials.
