Chemours Teflon® PTFE Grade FPD3584 Aqueous Dispersion  (discontinued **)
Categories: Polymer; Thermoplastic; Fluoropolymer; Polytetrafluoroethylene (PTFE)

Material Notes: DuPont PTFE FPD3584 is a negatively charged, hydrophobic colloid, containing approximately 60% (by total weight) of 0.05 to 0.5 mm polytetrafluoroethylene (PTFE) resin particles suspended in water. Seen as a milky white liquid, it also contains approximately 6% (by weight of PTFE) of a nonionic wetting agent and stabilizer. Viscosity at room temperature is approximately 20 cP. Nominal pH is 10.

DuPont PTFE FPD3584 dispersion is a generalpurpose impregnation grade of dispersion.

When properly processed, the PTFE resin in DuPont PTFE FPD3584 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

DuPont PTFE FPD3584 is normally used to impregnate packings for sealing and low friction applications. The small particle size, low surface tension and low viscosity aid in wetting of the braided yarn bundles. Typical substrates that can be impregnated include PTFE fibers, aramid, flax, glass, etc.

Chemours was formed from former DuPont performance chemicals businesses, including DuPont Fluoroproducts, in 2015.
