Virgin PTFE is a high performance polymer which is almost chemically inert, only being attacked under extreme conditions by molten alkali metals and certain fluorine compounds.
PTFE materials are suitable for a wide range of temperatures from cryogenic to 260°C and have excellent insulating capabilities and high dielectric properties. In this respect PTFE is a very successful gasket material.
