DONIFLON® 900E is an expanded PTFE sealing material with superior chemical resistance to
various media except molten alkali metals, fluorine gases and perfluorinated hydrocarbon fluids.
It is recommended for pharmaceutical and food industries. Its excellent compressibility enables
very good adaptability to pressure sensitive connections like ceramic, glass, plastic-lined piping as
well as uneven flanges.
