Error. Polytetrafluoroethylene is not resistant to high temperatures, but it is corrosion-resistant and has lubricating properties; it is used in most applications. Graphite gaskets are still required for high temperatures.

Wrong; polytetrafluoroethylene has extremely strong corrosion resistance, but it is not resistant to high temperatures

Polytetrafluoroethylene is used as a sealant because it is resistant to high temperatures and various types of corrosion. Polytetrafluoroethylene does indeed have corrosion resistance, but its typical operating temperature is below 150 degrees – is that considered a high temperature? If what you mean is a relatively high temperature, then this statement is fine and correct.

It can’t tolerate high temperatures; the regular version can withstand 100 degrees, while the modified version can handle 200 degrees. It is resistant to acids and alkalis
