Premium thermally conductive aluminum foil tape with acrylic adhesive for heat shielding, thermal management, and industrial sealing applications. UL 723 Class L rated.
The 3M™ Aluminum Foil Tape 431 is a high-performance industrial foil tape engineered for demanding applications across multiple industries. Featuring a dead soft aluminum foil backing combined with a highly engineered pressure-sensitive acrylic adhesive, this tape delivers exceptional thermal conductivity and heat dissipation capabilities. The tape is specifically designed to protect temperature-sensitive materials by efficiently dissipating heat and improving heating and cooling efficiency. With its superior conformability to curved and uneven surfaces, it provides reliable performance in challenging environments.
This professional-grade tape offers excellent durability and long-term adhesion while maintaining the ability to remove cleanly after harsh masking applications. The thermally conductive aluminum backing helps reduce hot spots and protects substrates from high temperature effects. Engineered to withstand exposure to flame, weathering, moisture, UV radiation, and various solvents, the 3M Aluminum Foil Tape 431 delivers consistent performance both indoors and outdoors. The tape is classified by UL to UL 723, Class "L" for low flammability rating and meets F.A.R 25.853(a) specifications.
Ideal for heat shielding of delicate components, heat reflecting applications, moisture barrier protection, light enhancement, seaming, sealing, and refrigerator/freezer coil attachment. The tape also provides excellent plastic protection against heat and UV exposure. Each case contains 16 rolls, making it economical for large-scale industrial operations and manufacturing facilities requiring consistent, reliable thermal management solutions.
