Teflon® PFA D 335D

About
DuPont™ Teflon ® PFAD 335D is an off-white aqueous perfluoroalkoxy (PFA) dispersion stabilized with a non-ionic surfactant. It is a general-purpose dispersion that can be used to impart some the unique properties of PFA 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 PFA resin in PFAD 335D is a melt flowable thermoplastic, providing superior properties typical of fluoropolymer resins: retention of properties after service at 260 °C (500 °F) and useful properties at -240 °C (-400 °F). PFAD 335D aqueous dispersion provides: inertness to nearly all industrial chemicals and solvents stability at high temperatures excellent dielectric properties excellent weatherability excellent anti-stick properties Typical 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 Holt melt adhesive for PTFE, PFA and FEP parts Metal coatings&&
