Polyken 225FR Flame Retardant Cargo Pit Duct Tape | 12 Mil | FAR 25.853(a) | DMS 1968E | Fokker FK05-006

A premium flame retardant cargo pit duct tape trusted by freight airline operators and aerospace MRO crews worldwide — combining the conformability and crisp hand-tear of a high-performance duct tape with the flame resistance required for use in aircraft cargo compartments. Tested and proven compliant with FAR 25.853(a)(1)(i) and approved to additional OEM specifications including DMS 1968E, Fokker FK05-006 & FK05-113, and Lockheed LCP-86-1226-A. Polyken 225FR is a 12 mil PE-coated cloth tape with a natural rubber-based adhesive engineered for cargo pit applications, seaming and repairing cargo compartment liner panels, covering pins and rivets, and patching, sealing, and bundling in challenging environments where high adhesion and flame resistance are critical. Its Deca-BDE free formulation meets environmental requirements while delivering moisture, solvent, and abrasion resistance. The tape tears cleanly by hand with a crisp, straight edge — no tools needed in the cargo compartment.
