DuPont™ Teflon ® PTFE DISP 35 is a milky white aqueous PTFE dispersion stabilized with an anionic dispersant. It is used for co-coagulation with various fillers to produce products with a range of strengths, porosities and colors required for the application. The use of reinforcing agents can offer such advantages as improved resistance to cut-through and abrasion, increased dimensional and form stability, higher rate of heat dissipation and greater resistance to wear. When properly processed, the PTFE resin in DISP 35 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 35 aqueous dispersion provides:
- ability for co-coagulation
- inertness to nearly all industrial chemicals and solvents
- stability at high temperatures
- excellent dielectric properties
- lowest coefficient of friction of any solid material
- non-stick characteristics
Typical Applications
DISP 35 is used in the preparation of blends for coating of high performance bearings and seals. DISP 35 can also be co-coagulated with special ingredients to be formed into specific end-uses, such as fuel cell electrodes.
Teflon ® PTFE DISP 35 meets the requirements of ASTM D 4441-98, type I, grade 2, class A.
