GORE™ SKYFLEX™ Aerospace Materials

Overview

GORE™ SKYFLEX™ Aerospace Materials are a portfolio of advanced expanded polytetrafluoroethylene (ePTFE) tapes and gaskets engineered for aerospace sealing, abrasion protection, corrosion prevention, and gap-filling applications. Developed for both civil and military aircraft, these lightweight, flexible, non-curing materials provide reliable sealing performance while simplifying assembly and reducing maintenance costs. They are widely specified by leading OEMs and operators for faying surface protection, access panels, fairings, fuel systems, and structural interfaces.
