PTFE sheet is great material for high-temperature and low-friction applications. PTFE is pretty much safe against most known elements and compounds. It is attacked only by the alkaline metals in the elementary state, by chlorine trifluoride, and by elementary fluorine at high temperatures and pressures. PTFE doesn’t dissolve in most solvents at temperatures up and around 300oC. Fluorinated hydrocarbons can cause an amount of expansion which is not permanent. Some oils which are highly fluorinated and at temperatures over 300oC can inflict a dissolving affect upon this excellent engineering plastic. PTFE is the most chemically resistant plastic yet known. Very few chemicals will react with it. Its mechanical strength properties are low compared to other engineering plastics such as nylon, but its properties do remain over a great temperature range. Its working temperatures are exceptional at -240o to +260oC. PTFE has outstanding thermal and electrical insulation properties. And, it is famous for its very low coefficient of friction. It is very difficult to make anything stick to PTFE without specific preparation.
It has a number of advantages that make it a good choice :
