Teflon® FEP TE-9568

Description
DuPont™ Teflon ® FEP TE-9568 fluoropolymer resin is a negatively charged, hydrophobic colloid containing approximately 54% (by total weight) of 0.1 to 0.30 µm fluorinated ethylene propylene (FEP) particles suspended in water. It also contains approximately 6% (by weight of FEP resin) of a nonionic wetting agent and stabilizer. Color is off-white and nominal pH is 10.0. Viscosity at room temperature is approximately 25 cP.

Teflon ® TE-9568 is a general-purpose dispersion. It can be used to impart some of the unique properties of Teflon ® FEP resin to end products that would be difflcult to make using traditional melt extrusion processes. It can be used to coat or impregnate porous structures or to make thin ?lms. It can be coated and melt bonded to polytetrafluoroethylene (PTFE) resin or used as a hot melt adhesive.

The Teflon ® FEP resin in TE-9568 is a true thermoplastic, providing superior properties typical of the fluoropolymer resins: retention of properties after service at 204°C (400°F), useful properties at -240°C (-400°F), chemical inertness to nearly all industrial chemicals and solvents, and excellent dielectric properties. Refer to Table 1 for typical property data.

Typical End Products
Teflon ® FEP TE-9568 is suitable for many end products, including: heat-sealable top coatings for PTFE-coated fabrics used for belting, circuit boards, or electrical insulation; cast film for capacitors or chemical barriers; and as a hot melt adhesive for bonding molded PTFE or FEP parts to themselves or to each other.
