3M 425 Conductive Metallic Tape, 50mm x 55m

A soft silver aluminium foil combined with a high performance synthetic acrylic adhesive offering excellent temperature and environmental resistance. Ideal for holding and sealing.

UL approval for class 'L' for low flammability
Suitable for long term indoor/outdoor applications
Reflective backing gives excellent radiation for both heat & light
Good sealant, with a very low moisture transmission rate
Heavy foil backing for rugged durability
Long term temperature resistance -55°C to +150°C

The 3M 425 Aluminium Tape features a pressure sensitive acrylic adhesive makes it easy to apply with soft aluminium foil backing. Its used for a number of applications across a broad range of industries. Making it ideal for heat shielding, heat reflections, light enhancement, chemical milling, seaming and sealing.

The soft aluminium is thermally conducting 3M 425 Foil Tape dissipates the heat over the surface of the foil backing to reduce heat spots and protects the subject from the effects of high temperatures. The 425 tape is capable of withstanding temperatures of 149°C without losing any of its fundamental properties.

Acrylic adhesive provides long term durability
Soft aluminium foil backing molds to curved and uneven surfaces
Helps dissipate heat
Improves heating and cooling efficiencies
Chemical resistance helps protect surfaces during de-painting process and other chemical masking operations.
UL and UL 746C and Classfied by UL to UL 723

Extreme Hot and cold temperature versatility. 3M foil tape works in temperatures to which other tapes would diminish. Performing in cold conditions allows this 3M tape to be a market leader, as other tapes see the adhesive harden and begin to lose sticking strength. On the contrary, extreme heat can melt adhesives of tapes, but not the 3M foil tape making it versatile for most applications.

An Acrylic Adhesive backing. This 3M Aluminium foil tape is coated in a superior acrylic adhesive, which works well in extreme cold and heat conditions. This matters when comparing to most duct tapes that are made with a rubber adhesive. This is then known to delaminate from its backing in these extreme conditions. Other adhesives can offer greater resistance but will lack mechanical strength, poor ageing resistance and UV light.

Longevity of foil tape. Within the construction industry, the use of pressure sensitive tapes is often used in hard to reach areas. This means they can't be easily replaced or repaired. The acrylic adhesive on the 3M aluminium foil tape offers better cohesion, adhesion and thermal properties.

There is no electrolytic corrosion factor associated with these products.
