Higher cell operating temperatures (i.e. ~70-80 掳C) assist in water removal in vapour form and hence GDL hydrophobisation effect is not significant. Experimental results showed that a low amount of PTFE-coating improves the FC-performance at both low and high humidity conditions. It was ...
·All AVANNTO valves are pressure tested to 110% of rated pressure to assure bubble tight shutoff. ·All AVANNTO butterfly valves are pin-less design ·Chemical resistant, weather resistant, abrasion and impact resistant coating ·Internal disc-to-stem connection ...
Its non-stick character has long been evidenced by its everyday use as an interior coating in cooking utensils. Its inability to form a true melt long ago forced the development of special extrusion, molding, and calendering processes in which the PTFE powder is pressed, then, sintered with ...
Dopamine which has been considered as crucial component in adhesives, can form a firm coating on various substrates by self-polymerization under the presence of oxygen [16]. On the one hand, by simple deposition process, dopamine is able to coat membrane surface as a modifier [17], [18], ...

Previous studies have shown that partially coating electrode surfaces with patterns of ‘islands’ of hydrophobic tetrafluoroethylene (PTFE; Teflon) may lead to more energy efficient gas generation. This occurred because the gas bubbles formed preferentially on the PTFE, thereby freeing up the catalytica...
flow readily even above itsmelting point. Molded parts can be made by compressing and heating fine powders mixed withvolatilelubricants. Metallic surfaces can be sprayed or dipped with aqueous dispersions of PTFE particles to form a permanent coating. Dispersions of PTFE can also be spun into ...
Typical ApplicationsDISP 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 ...
Expanded PTFE gasket tape are made of pure PTFE, can be widely used in the transport and sealing of industrial fluids. It is the most cost-effective alternative to sheet gasketing for large equipment flanges. Because it is a form-in-place gasket, so it nearly can be ...
