3M Aluminium Tape, 50mm Width, 55mm Length - 4255055


This aluminium tape serves as a conductive joining and sealing solution for electrical and mechanical assemblies, delivering a metallic backing with an adhesive layer suited to demanding industrial environments. It is intended for applications where a conductive, thin foil is required to maintain continuity and provide a protective metallic surface across joints or seams.

Features and Benefits:


• Conductive foil backing provides electrical continuity for grounding
• Acrylic adhesive offers strong bond to varied surfaces
• Operates effectively between -54°C and +149°C
• Tensile strength of 49N/cm supports mechanical stability
• Thickness 0.12mm maintains minimal profile for tight fits
• Silver finish enhances reflectivity and surface coverage

Applications


• Suitable for EMI shielding aluminium foil tape in electronic cabinets
• Ideal for HVAC and ducting repairs requiring conductive sealing
• Used for electrical earthing where thin aluminium tape is needed
• Can be used for folding and overlap joints on metal panels
• Used with sensor enclosures to maintain conductive continuity

How does the adhesive perform on different substrates?


The acrylic adhesive is formulated to adhere to many common substrates, providing persistent contact and conductive transfer where foil contact is maintained.

What mechanical loads can the tape tolerate in lap joints?


With a tensile strength of 49N/cm the foil resists longitudinal pull and helps stabilise overlaps under shear and moderate tension.

Will the tape resist temperature cycling in industrial systems?


The material stays functional across a wide range from -54°C up to +149°C, preserving adhesive contact and foil integrity during thermal excursions.

Is the foil electrically conductive through its body?


The aluminium backing is conductive, enabling use for earthing paths and electrical continuity where direct contact is ensured.
