| Teflon® PTFE DISP 33 | |||
| Polytetrafluoroethylene | |||
| Product Description: | |||
| DuPont™ Teflon ® PTFE DISP 33 is a milky white aqueous PTFE dispersion stabilized with a non-ionic surfactant. DISP 33 is typically used to coat woven glass cloth and has been especially formulated to provide void-free coatings with enhanced surface smoothness, adhesion, gloss and weldability. When properly processed, the PTFE resin in DISP 33 exhibits the superior properties typical of the fluoropolymer resin: retention of | |||
| properties after service at 260 °C (500 °F), and useful properties at -240 °C (-400 °F). | |||
| DISP 33 aqueous dispersion provides: | |||
| enhanced surface smoothness, adhesion, gloss and weldability | |||
| inertness to nearly all industrial chemicals and solvents | |||
| stability at high temperatures | |||
| excellent dielectric properties | |||
| lowest coefficient of friction of any solid material | |||
| excellent weatherability | |||
| non-stick characteristics | |||
| Typical Applications | |||
| Coated woven fiber-glass fabric used in architectural, high-performance industrial, food processing and electronics applications | |||
| Impregnated packing made from braided fibers for severe chemical and thermal service | |||
| Cast film for capacitor dielectrics or chemical barriers | |||
| Surface coatings for metallic or other high-temperature substrates | |||
| Teflon ® PTFE DISP 33 meets the requirements of ASTM D 4441-04, type II, grade 6, class A. | |||
