Teflon™ FEPD 121 is an off-white aqueous fluorinated ethylene propylene (FEP) dispersion stabilized with a non-ionic surfactant. It is a general-purpose dispersion that can be used to impart some the unique properties of FEP to end products that would be difficult to make using traditional melt extrusion processes. It can be used to coat or impregnate porous structures, or to make thin films. It can be coated and melt bonded to polytetrafluoroethylene (PTFE) resin or used as a hot melt adhesive. The FEP resin in Teflon™ FEPD 121 is a melt flowable thermoplastic, providing superior properties typical of fluoroplastic resins. Applications: Heat-sealable top coatings for PTFE-coated fabrics for belting, circuit boards, architectural fabrics, and electrical insulation. Cast film for capacitor dielectrics or chemical barriers. Hot melt adhesive for PTFE, PFA, and FEP parts. Metal coatings. Properly processed products (sintered at high temperatures common to the industry) made from Teflon™ FEPD 121 resin can qualify for use in contact with food in compliance with FDA 21 CFR 177.1550 and European Regulation (EU) No. 10/2011.Information provided by Chemours. |
