Description
5 mil clear polyester film with high tensile, tear and impact strength. It is inert in water and moisture/ vapor resistant. Material is unaffected by oils, greases and volatile aromatics.
Application Surface
Composite Milling, Moisture Barrier
Substrate
Polyester
Thickness
5 MIL (paper, polyester)
Application
Applied to aluminum or stainless steel under galley and lavatory areas on commercial aircraft to prevent water damage or corrosion of the metal. Can be die-cut for aircraft windows during stripping operations.
Applied to one side of fiber or aluminum honeycomb core material to hold in place on vacuum table for milling opposite side.
