3M Aerospace (St. Paul, Minn.) has developed a Polyurethane Protective Tapes for use in aircraft interiors to protect exposed sections of lavatories, galleys, floor panel joints and doorways from moisture incursion. These flame retardant tapes are constructed of an extremely tough, puncture-resistant thermoplastic elastomer coated with a pressure-sensitive adhesive. The tapes provide a durable and flame-resistant barrier that 3M prevents costly corrosion damage to aircraft floor systems, and can be installed for a variety of applications, including seam sealing, wide wet area protection and beam protection. High elongation gives the tapes good conformability, providing effective coverage of contoured areas, and their dual liner construction results in better productivity and fewer wrinkles or bubbles during application. The tapes also meet the FAA’s expected new policy statement for 14CFR 25.853 that will provide standardized testing and establish acceptable methods of compliance for flame resistance.
