3M 4380 Silver General Purpose Aluminum Foil Tape

4380

3M™ Aluminum Foil Tape 4380 is a 3.25 mil industrial grade metal foil tape used for general purpose applications. This tape minimizes vapor transmission making it a good sealant. Other uses include light reflection, heat shielding, and thermal conducting.

  • Resists flame, moisture, weather, UV degradation and many chemicals
  • Thermally conductive tape reflects and dissipates radiant heat to protect heat sensitive components or surfaces
  • Low moisture vapor transmission rate offers excellent sealing and patching performance
Color: Silver
Backing/Carrier Material: Dead Soft Aluminum Foil
Adhesive Type: Acrylic
TotalThickness: 3.25 mil
