3M Conductive Metallic Tape, Aluminium Foil Backing, 38mm x 55m, Acrylic Adhesive, Heat Resistant up to 149°C 425 38MMX55M

3M 425 38MMX55M Conductive Metallic Tape is a premium aluminium foil tape designed for demanding industrial and electrical applications requiring robust EMI/RFI shielding and grounding solutions. With a backing material of conductive aluminium foil and a thickness of 0.12mm, this metallic tape combines electrical conductivity with mechanical flexibility.

The tape features an acrylic adhesive that provides an adhesion strength of 5.1 N/cm, ensuring rapid initial tack and long-term bond reliability. Its tensile strength of 49 N/cm allows it to withstand mechanical stresses and maintain seam integrity under vibration or handling conditions. The temperature tolerance ranges from -54°C to 149°C, making it suitable for environments spanning cold storage to high-heat zones.

This tape conforms easily to uneven and curved surfaces due to its thin profile and flexible aluminium backing, enabling effective bonding and electrical continuity across conductive seams. It is widely used in EMI/RFI shielding in electronic control cabinets, grounding on chassis and panels, sealing ductwork, and conductive bonding in cable harnesses. Automation and sensor applications benefit from its noise mitigation properties.

It does not comply with EN legislation and has no special certifications or approvals. Its silver colour and conductive backing make it ideal for industrial electrical and mechanical assembly tasks requiring durable conductive tapes.

The aluminium foil backing provides highly conductive EMI and RFI shielding. The acrylic adhesive offers strong adhesion and durability under industrial conditions. Designed for thermal resilience with a maximum operating temperature of 149°C.

High tensile strength supports mechanical durability and seam integrity. Thin and flexible profile enables application to irregular surfaces. Used for grounding, bonding, repairing thermal insulation & ductwork. Application sectors include electronics manufacturing, HVAC, automation, and industrial repair.

This 3M 425 tape is a reliable choice for professionals seeking a conductive metallic tape that balances electrical performance, thermal endurance, and mechanical strength.
