科慕(原杜邦)PFA乳液PFAD335D

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 fluoroplastic resins:
retention of properties after service at 260 °C (500 °F) and useful
properties at 240 °C (400 °F).

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
