2. Polytetrafluoroethylene - Wikipedia

   en.wikipedia.org/wiki/Polytetrafluoroethylene

   Because of its extreme non-reactivity and high temperature rating, PTFE is often used as the liner in hose assemblies, expansion joints, and in industrial pipe lines, particularly in applications using acids, alkalis, or other chemicals. Its frictionless qualities allow improved flow of highly viscous liquids and for uses in applications such ...

   Tungsten is often used in high temperature applications as well as for filaments in electron/ion optics. It becomes brittle from work hardening when mechanically deformed, or subjected to very high temperatures. Molybdenum and tantalum are useful for high temperature applications. [3] Titanium and niobium are good materials.
