Product Description

DuPont™ Teflon® FEPD 121 Fluoropolymer Dispersion

More Information:

Teflon® FEP resin is a fluorinated ethylene propylene resin that meets the ASTM Standard Specification for
FEP—Fluorocarbon Molding and Extrusion Materials under ASTM Designation D2116-95a. It is available
as pellets or as stabilized aqueous dispersions. Applications for this family of resins include molding, melt
extrusion, coatings and impregnating. Products made from Teflon® FEP are known for their excellent
chemical resistance, superior electrical properties, and high service temperatures of up to 204°C (400°F).
In addition, Teflon® FEP provides outstanding low-temperature toughness and unique flame resistance.
Teflon® FEP fluoropolymer resins are processed by conventional melt-extrusion techniques and by injection,
compression, transfer, and blow-molding processes.

The FEP resin in FEPD 121 is a melt flowable thermoplastic, providing superior properties typical of fluoropolymer resins: retention of properties after service at 204°C (400°F) and useful properties at –240°C (–400°F).

 FEPD 121 aqueous dispersion provides:

• Inertness to nearly all industrial chemicals and solvents
• Stability at high temperatures
• Excellent dielectric properties
• Excellent weatherability

Typical Applications Include:

•  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
