Industrial-grade aluminum foil tape with acrylic adhesive for heat shielding, light reflection, and sealing applications. Features thermally conductive backing, excellent durability, and UL 723 Class L flammability rating.
The 3M™ Aluminum Foil Tape 431 is a high-performance industrial foil tape designed for numerous applications across a broad range of industries. Comprised of a dead soft aluminum foil backing with a highly engineered pressure sensitive acrylic adhesive, it is ideal for heat shielding, heat reflecting, light enhancement, seaming and sealing applications. This thermally conductive tape helps dissipate heat and improves heating and cooling efficiency to protect temperature sensitive materials from extreme conditions.
Featuring a dead soft aluminum foil backing that conforms to curved and uneven surfaces, combined with a highly engineered acrylic adhesive that provides long term durability while removing cleanly after harsh masking applications, this tape offers exceptional performance in demanding industrial environments. The tape withstands exposure to flame, weathering, moisture and UV radiation, making it suitable for both indoor and outdoor applications. Classified by UL to UL 723, Class "L" for low flammability rating and meeting F.A.R 25.853(a), it operates reliably across a wide temperature range from -65°F to 300°F (-54°C to 149°C).
This professional-grade tape is specifically designed for industrial and occupational use, providing excellent aging performance both indoors and outdoors. With its superior heat and light reflective properties, it protects surfaces and enhances lighting efficiency while maintaining a strong and reliable bond under high heat and humidity exposure. Each case contains 36 rolls, with each roll measuring 1 inch wide by 60 yards long with a 3.1 mil overall thickness, making it ideal for large-scale industrial operations and manufacturing facilities.
