3M 7010295790 Aluminum Foil Tape 4380, Silver, 4 in x 60 yd, 3.25 Mil

3M™ Aluminum Foil Tape 4380 is a self-wound, general purpose, aluminum foil backed tape combined with a pressure sensitive acrylic adhesive. This tape is ideal for general purpose sealing, holding, splicing or masking applications requiring the protection from heat or flame offered by a foil backing.

Protect Sensitive Parts From Heat and Flame
3M™ Aluminum Foil Tape 4380 is a general purpose, aluminum foil tape comprised of a 2.0 mil dead soft aluminum foil backing and a pressure sensitive acrylic adhesive. This tape is malleable and conforms well to uneven, curved or irregular surfaces. The aluminum backing offers and excellent reflective surface and is thermally and heat conductive for heating and cooling efficiency. It reflects light to enhance lighting efficiency and resists flame, moisture, weather, dust, UV degradation and many chemicals to provide long-lasting durability.

Recommended Applications


General use holding, patching and sealing applications
Light reflecting
Heat shielding applications
Moisture and vapor barrier
Thermal conducting


All Around Performance Under a Wide Range of Temperatures
3M™ Aluminum Foil Tape 4380 is coated with a pressure sensitive acrylic adhesive designed to bond to a broad range of substrates. This tape adheres immediately upon contact and can perform under a wide spectrum of temperatures ranging from -30°F/-34°C to 300°F/149°C. Due to its low moisture transmission rate, this tape offers excellent sealing and patching performance. 3M™ Aluminum Foil Tape 4380 is UL 723 approved.
