Product Description
3M 431 25MMX55M conductive metallic aluminium foil tape is designed for demanding industrial and electrical applications requiring reliable heat and electrical conductivity. This tape combines a thin 0.08mm aluminium foil backing with an acrylic adhesive that provides excellent adhesion strength of 4.5N/cm, making it suitable for long service life both indoors and outdoors.
Its shiny silver colour and aluminium backing provide superior thermal and electrical conductivity, reflecting radiant heat while dissipating it to reduce hotspots. The tape withstands a broad temperature range from -54°C to a maximum of 149°C without losing key properties, enabling diverse use cases such as heat shielding, electrical coil maintenance, splicing thin gauge foils, and masking in electroplating without contaminating baths.
The robust acrylic adhesive maintains bonding strength in extreme heat and cold conditions, outperforming conventional tapes that lose adhesion in such environments. The pliable aluminium material allows the tape to conform to irregular surfaces, providing flame, moisture, and UV resistance which is essential for industrial, electronics, HVAC, and manufacturing environments.
The tape length of 55 meters allows extensive application coverage. Adhesive acrylic ensures durability and strong mechanical holding. Minimum operating temperature is -54°C ensuring performance in cold environments. The tape’s conductive quality makes it valuable for electrical circuitry and grounding applications.
Reflective properties improve light efficiency where applied. Aluminium foil backing resists fire, moisture, and weather degradation. Offered with 25mm width for precision application.
This metallic conductive tape is ideal for professional use in electrical assembly, heat management, manufacturing, and industrial maintenance. It provides a trusted balance of conductivity, strength, and thermal protection.
