100% PTFE resistant to all corrosive media
100% PTFE gaskets are highly resistant to all corrosive media, including acids, alkalis, and solvents. PTFE (polytetrafluoroethylene) is a synthetic polymer with excellent chemical resistance properties, making it an ideal material for gaskets used in applications where contact with corrosive media is common.
PTFE gaskets are made from a single material, which means that they do not have any fillers or binders that could potentially react with corrosive media. This makes them highly resistant to a wide range of chemicals, including strong acids, bases, and oxidizing agents.
