Abstract
Abstract A sealing tape for sealing the gaps between the edge of an opening in an aircraft fuselage and the lid closing said opening comprising a sealing tape that is a one-piece porous polymeric material having a relatively wide flat portion and a narrower enlarged bulb portion. In addition, the porous polymeric material may be filled or plated with metal powder or filings so that the one-piece sealing tape is rendered conductive.
