Premium 3M aluminum foil tape with thermally conductive acrylic adhesive for heat shielding, chemical masking, and thermal protection. 150mm x 55m roll rated for -65°F to 300°F with UL certification.
3M™ Aluminum Foil Tape 425 is a premium industrial-grade foil tape engineered for demanding applications across aerospace, automotive, appliance, construction, electronics, and metalworking industries. This versatile tape features a dead soft aluminum foil backing combined with a highly engineered pressure-sensitive acrylic adhesive that delivers exceptional thermal conductivity and chemical resistance. The tape is specifically designed to dissipate heat effectively, improving heating and cooling efficiency while protecting temperature-sensitive materials from thermal damage.
The 150mm wide by 55-meter long roll delivers superior performance in heat shielding, chemical masking, moisture barrier applications, and light reflection enhancement. With a backing thickness of 2.8 mil (0.07mm) and total tape thickness of 4.6 mil, this single-sided adhesive tape withstands extreme temperatures ranging from -65°F to 300°F (-54°C to 149°C), making it ideal for both indoor and outdoor applications. The dead soft aluminum foil backing conforms easily to curved and uneven surfaces, providing excellent coverage and reliable adhesion.
This product meets rigorous industry standards including UL 746C recognition, UL 723 classification for low flammability rating (Class L), L-T-80C certification, and FAR 25.853(a) compliance. With a 24-month shelf life and tensile strength of 28 lb/in (49 N/100mm), the tape maintains its integrity through exposure to flame, weathering, moisture, UV radiation, and harsh chemical environments. Each case contains 2 rolls, providing 110 meters of total coverage for large-scale industrial projects.
