DuPont Teflon® PFA Grade 335 Aqueous Dispersion

 

Subcategory: Fluoropolymer; Thermoplastic; PFA

Key Words: DuPont Fluoroproducts; DuPont PFA

Material Notes:
Teflon® PFA 335 (formerly TE-9946) is a negatively charged, hydrophobic colloid, containing approximately 60% (by total weight) of 0.05 to 0.5 µm perfluoroalkoxy (PFA) resin particles suspended in water. A milky white liquid, Teflon® PFA 335 also contains approximately 5% by weight of a nonionic wetting agent and stabilizer (based on the weight of the PFA solids). Viscosity at room temperature is approximately 20 cP. Nominal pH is 10.

Unlike Teflon® PTFE dispersions, the resin in Teflon® PFA 335 is a true thermoplastic and will exhibit some flow above its melting point. When properly processed, the PFA resin in Teflon® PFA 335 exhibits the superior properties typical of the fluoropolymer resins: retention of properties after service at 260°C (500°F), useful properties at –240°C (–400°F), chemical inertness to nearly all industrial chemicals and solvents, and low friction and antistick surfaces. Dielectric properties are outstanding and stable with frequency and temperature.

Applications

Teflon® PFA 335 is a general-purpose product used in a variety of coating applications. It can also be used as a heat sealable topcoat.
