Lightweight Aerospace Gap Filler Foam

Urethane Seal and Gap Filler

Foam-Comb Gap Seals

Primarily used in the aerospace industry, General Plastics’ Foam-Comb is a lightweight urethane seal and gap filler which serves as a flexible cushion between panels that expand and contract repeatedly. It is optimal for use as an aerospace and aviation interior material, particularly in passenger cabin applications and where noise reduction is beneficial.

The open-cell Foam-Comb consists of a combination of flexible foam and Nomex® honeycomb material. It is flexible in height and retains marginal strength in the T-direction (thickness) while remaining flexible and resilient in the ribbon direction (length). The Foam-Comb is flame retardant (meets FAR 25.853 standards) and can be supplied with double back tape attachments and RTV friction enhancer strips.foam-comb
