Why Use PTFE As A Seal? It is chemical resistant. Pure PTFE can be used in the most corrosive of environments and will not contaminate the most sensitive medium. PTFE is completely insoluble and has very high intrinsic purity and can be manufactured with no contamination for ultra-pure or corrosive applications. It is completely resistant to attack by all chemicals with the exception of molten alkali metals and a few fluorine compounds at elevated temperatures and pressures. It is unaffected by lubricants, hydraulic fluids, aircraft/rocket fuel and atmospheric conditions.
