Polyken 297 Cargo Pit Tape
Polyken 297 Cargo Pit Tape is a flame-retardant fiberglass cloth tape designed for sealing and repairing aircraft cargo compartment liners.
Polyken 297 Cargo Pit Tape is engineered for high-load aerospace environments where flame resistance and mechanical strength are required. The tape features a white fiberglass cloth backing combined with a high-tack rubber-based adhesive.
Its 8 mil construction delivers a balance of durability and conformability, allowing the tape to wrap securely around seams, pins, rivets, and complex contours without lifting or flagging.
Polyken 297 maintains a strong seal under cargo movement and vibration while supporting compliance with FAA cargo compartment fire safety regulations.
What is Polyken 297 Cargo Pit Tape used for?
Polyken 297 is used for sealing cargo pit liners, covering rivets and pins, and repairing seams in aircraft cargo compartments.
Is Polyken 297 flame retardant?
Yes. Polyken 297 complies with FAR 25.853(a) and FAR 25.855(d) requirements for cargo compartment flame resistance.
Why is rubber adhesive important in cargo pit applications?
The rubber-based adhesive provides immediate, aggressive bonding and resists edge lifting under vibration and load.
- Flame-retardant fiberglass cloth backing
- High tensile strength for cargo compartment durability
- Aggressive rubber-based adhesive
- Resists flagging on rivets, pins, and seams
- Conformable around curves and complex surfaces
- Designed specifically for aircraft cargo pit use
