Premium 3M aluminum foil tape designed for cold weather sealing and bonding from -10°F to 260°F, featuring 1.8 mil foil backing and acrylic adhesive for industrial HVAC, ductwork, and thermal applications.
3M™ Aluminum Foil Tape 3380 is a premium multi-purpose foil tape engineered for demanding cold weather applications and high-performance sealing in extreme temperature environments. This industrial-grade tape features a nominal 1.8 mil aluminum foil backing coated with a pressure-sensitive acrylic adhesive specifically formulated to bond and seal in temperatures as low as -10°F/-23°C, while maintaining excellent performance up to 260°F/127°C. The tape excels in a wide variety of applications including fibrous ductboard, sheet metal ducts, blankets, and general-purpose heat shielding and light reflecting applications across aerospace, appliance, construction, maintenance repair and operations (MRO), specialty vehicles, and transportation industries.
The 3M Aluminum Foil Tape 3380 combines superior flexibility with exceptional durability, conforming smoothly to curved and irregular surfaces without requiring special tools or application methods. The hand-tearable construction and easy-release natural kraft paper liner make on-site installation convenient and efficient. With a tensile strength of 10 lb/in (17.5 N/100mm) and only 4% elongation at break, this tape provides reliable holding power for extended periods with outstanding aging properties that resist lifting, curling, and degradation from moisture, ultraviolet rays, and chemical exposure.
UL723 classified with a 10/10 Flame/Smoke rating, this tape is backed by exclusive 3M technical expertise and application advice. The product comes in a convenient 16 rolls per case packaging, with each roll measuring 72mm in width and 45 meters in length. Perfect for industrial professionals who demand consistent performance in challenging environmental conditions, the 3M Aluminum Foil Tape 3380 delivers long-lasting protection and reliable sealing solutions across diverse applications and industries.
