Teflon® PTFE DISP 40
聚四氟乙烯
DuPont Fluoropolymers
产品说明:
DuPont™ Teflon ® PTFE DISP 40 is a milky white aqueous PTFE dispersion stabilized with a non-ionic surfactant. It is designed to provide enhanced shear stability and can be used in coating and additive applications. It imparts properties unique to PTFE resin to porous structures, as well as to base materials when used as an additive. When properly processed, the PTFE resin in DISP 40 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 40 aqueous dispersion provides:
Typical Applications
DISP 40 aqueous dispersion provides:
- higher shear stability for improved mixing and processing
- inertness to nearly all chemicals and solvents in commercial use
- 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
- Formulated surface coatings for metallic or other high-temperature substrates
- Anti-drip additive for plastics
- Binder for battery anode or cathode matrixes
Teflon ® PTFE DISP 40 meets the requirements of ASTM D 4441-98, type I, grade 2, class A.
