  PTFE gaskets
Chemical suitability: PTFE products
The chemical resistance of virgin Fluolion® PTFE is almost universal. It is suitable for sealing duties with
all chemical media – with the exception of molten alkali metals, fluorine gas and any materials that may
generate these at the operating temperatures and pressures involved.
However, Fluolion PTFE materials that contain fillers to enhance their mechanical performance may have
a lower resistance to certain chemical media than virgin PTFE. Therefore, prior to the use of these filled
products, please check chemical compatibility with our technical services team.
