PRODUCT FAQ
-
What makes 3M™ Heavy Duty Aluminum Foil Tape different from regular tape?
3M™ Heavy Duty Aluminum Foil Tape is made with a strong polyethylene backing and coated with synthetic rubber adhesive, which makes it much more durable than regular tapes. It can also withstand extreme temperatures and weather conditions.
-
Can I use this tape for HVAC applications?
Absolutely! In fact, our Heavy Duty Aluminum Foil Tape is specifically designed for HVAC ductwork sealing and repair. Its high-performance capabilities make it ideal for even the toughest jobs.
-
How long does a roll of 3M™ Heavy Duty Aluminum Foil Tape last?
While it ultimately depends on how often you use it, one roll of the tape measures at 60 yards in length--enough to last you through multiple projects or repairs. Plus, since it's so heavy duty, you shouldn't have to worry about replacing it too frequently.
3M™ Heavy Duty Aluminum Foil Tape 438 is a reliable solution for heat dissipation and substrate protection. It is made of a dead soft, thermally conductive aluminum backing that reduces hot spots and withstands high temperatures. The tape is coated with a highly engineered acrylic adhesive that maintains a strong bond even when exposed to high heat and humidity. It can also withstand moisture, weathering, UV, and solvents, making it suitable for indoor and outdoor use.
3M™ Aluminum Foil Tape 438 is UL Recognized to UL 746C (File E 122798) and Classified by UL to UL 723 "L" for low flammability rating (File R 7311). It meets F.A.R 25.853(a) and has a temperature use range of -65°F to 300°F (-54°C to 149°C).
