Its strong adhesive and heat-resistant metallic backing make it ideal for the aircraft environment, and while it resembles duct tape, it is far more advanced and expensive, often costing hundreds of dollars per roll. Though seeing it on planes can alarm passengers, its use is approved by aviation authorities like the FAA for temporary fixes in non-critical areas.
