PTFE is a good choice. PolyTetraFluoroEthylene is generally chemically resistance and resists high temperatures (for a polymer anyway, melting point is 327C). The most famous brand of PTFE is Teflon (R) made by DuPont.
Another good choice is PVDF, PolyVinyliDeneFluoride also known as Kynar or Hydar. It is easier to melt and coat and has excellent chemical resistance, but the melting temperature is lower, about 140C.
Good luck!

Some of the PTFE compounds have good anti corrosion propoerties at high temps, like teflon. Kynar is another possibility, but not sure what mechanical properties you need.
