Shop 3M High Temperature Aluminum Foil Tape 433L Silver 3 inch In Iraq Best Prices
Premium high-temperature aluminum foil tape with silicone adhesive, withstands up to 600°F, ideal for heat shielding, sealing, and splicing in aerospace, automotive, and industrial applications. 3 rolls per case, 60 yards each, 3 inches wide.
The 3M High Temperature Aluminum Foil Tape 433L is a premium linered aluminum foil tape specifically engineered for demanding heat shielding applications where extreme temperatures are a critical concern. This dead soft aluminum foil tape is coated with a clear silicone pressure-sensitive adhesive that provides exceptional bonding performance to a wide variety of surfaces, even in high-temperature environments where conventional adhesive tapes fail. The tape features a 3.5 mil total thickness with a 2 mil aluminum foil backing and 1.5 mil adhesive thickness, delivering superior thermal conductivity and heat dissipation capabilities.
Designed to withstand limited exposure up to 600°F (316°C), this tape excels in seaming, splicing, and sealing applications across aerospace, automotive, appliance, electronics, and general industrial sectors. The dead soft aluminum foil backing conforms seamlessly to curved and uneven surfaces, making it ideal for wrapping thermal insulation, splicing jumbo rolls, holding the last lap of narrow width rolls during metal annealing, and covering heating elements or wires to distribute heat evenly. With an operating temperature range from -65°F to 600°F (-54°C to 316°C) and elongation at break of 3.5%, this tape maintains its integrity across extreme thermal cycles.
This linered version is specifically designed for die-cutting operations and comes packaged as 3 rolls per case, each measuring 60 yards in length and 3 inches in width. The tape meets the flame resistance requirements of F.A.R. 25.853(a) and is recognized as a UL component (file QQQW2.MH122798), making it suitable for aerospace and safety-critical applications. With an 18-month shelf life and easy-release film liner, the 3M High Temperature Aluminum Foil Tape 433L provides reliable, consistent performance in the most demanding industrial applications.
