Foam Tape

Aerospace Foam Tape for Aircraft Sealing & Vibration Damping

Foam tape provides compressible, conformable sealing, cushioning, and vibration damping in aircraft assembly and maintenance applications where rigid materials cannot conform to irregular surfaces or accommodate differential thermal expansion. Closed-cell foam tape provides environmental sealing between mating surfaces; open-cell formulations are suited to cushioning and acoustic insulation applications.

SkyGeek stocks aerospace-grade foam tapes for aircraft gasketing, panel sealing, vibration isolation, and surface protection. For complementary sealing products including polysulfide, silicone, and polyurethane aviation sealants, see SkyGeek's aerospace sealants category.

Types of Aerospace Foam Tape

Closed-Cell Foam Tape

Compressible, non-water-absorbing foam tape for sealing gaps between mating panels, fairings, access doors, and structural interfaces. Provides environmental sealing against moisture, air, and dust ingress.

Open-Cell Foam Tape

Permeable foam tape for cushioning, acoustic absorption, and low-compression applications where complete environmental sealing is not required.

Double-Sided Foam Tape

Foam tape with adhesive on both faces for bonding and sealing simultaneously, including mounting lightweight components, attaching trim pieces, and sealing gap interfaces in aircraft interiors and structures.

Aviation Applications

Fairing and panel gap sealing
Access door and cowling perimeter sealing
Avionics bay vibration isolation mounting
Interior trim and panel cushioning
Acoustic insulation mounting
Control surface gap sealing

Buying Considerations

Cell structure: Closed-cell for environmental sealing; open-cell for cushioning and acoustic applications.
Compression set: Select foam with low compression set for long-term sealing where the foam must maintain sealing force over time.
Temperature range: Verify temperature resistance, particularly for engine-adjacent applications.
Thickness: Match foam thickness to the gap size being sealed. Excessive compression reduces seal effectiveness.

FAQs

Q: What type of foam tape is used for aircraft panel sealing?

A: Closed-cell foam tape is used for sealing aircraft panel gaps, access door perimeters, and fairing interfaces. Closed-cell construction provides environmental sealing against moisture and air ingress without absorbing water. Confirm tape thickness, compression ratio, and adhesive compatibility with your specific application requirements.

Q: Can foam tape be used for vibration isolation of aircraft avionics?

A: Yes. Foam tape is used in avionics bay applications for cushioning and vibration isolation mounting. Select foam grade based on required compression characteristics, temperature range, and the weight of the mounted equipment. Verify the application against the aircraft's avionics installation documentation.

Q: What is the difference between open-cell and closed-cell foam tape for aircraft?

A: Closed-cell foam has sealed cells that resist moisture absorption and provide environmental sealing under compression, which is the correct choice for panel gap sealing. Open-cell foam is compressible and permeable for cushioning and acoustic absorption, but does not provide an environmental seal.
