3M Metallic Tape, 38mm Width, 55m Length - 425 38MMX55M


This metallic tape is a conductive aluminium foil product designed for electrical and electronic work where EMI/RFI attenuation, grounding and thermal resilience are required. It combines a metal backing with an acrylic adhesive to provide conductive contact and is intended for use across a range of industrial environments, including repair, shielding and bonding tasks.

Features and Benefits:


• Conductive backing enables effective EMI shielding and grounding
• Acrylic adhesive offers strong tack with 5.1 N/cm adhesion force
• Heat-tolerant construction resists temperatures from −54°C to 149°C
• High tensile strength of 49 N/cm sustains mechanical stress
• Thin profile at 0.12mm maintains flexibility for conforming surfaces

Applications


• Suitable for EMI/RFI shielding in control cabinets and enclosures
• Ideal for establishing electrical earthing on chassis and panels
• Used for sealing and repairing ductwork and thermal insulation joints
• Can be used for bonding conductive seams on cable assemblies
• Used with sensors and actuators in automation equipment for noise mitigation

How does the tape behave when applied to uneven substrates?


Its 0.12mm thickness and aluminium foil backing allow it to conform to curved and irregular surfaces while maintaining conductive contact across the joint.

What temperature conditions can it tolerate during continuous operation?


It remains functional across a wide temperature range from −54°C up to 149°C, making it suitable for both cold storage and elevated-temperature zones.

How robust is the tape against mechanical strain after application?


With a tensile strength of 49 N/cm, it withstands significant pulling forces and helps maintain seam integrity under vibration or handling.

What adhesive performance can be expected immediately after application?


The acrylic adhesive delivers an initial adhesion strength of 5.1 N/cm, providing prompt tack for positioning and long-term bond retention.

Is the electrical continuity through the tape suitable for grounding tasks?


Yes

the conductive aluminium backing provides a low-resistance path for earthing and conductive shielding when applied correctly.
