INSTRUCTIONS FOR THE USE OF THE CHEMICAL RESISTANCE LIST
This chemical resistac chart is only intended as a guide. Changes in the composition of the medium or special working conditions could lead to deviations. If there is any doubt, it is advisable to test the behaviour of the material under specific working conditions, by means of a pilot installation. No guarantees can be given in respect of the information contained in this chart. The data shown is based upon information available at the time of printing, but it may, however, be revised from time to time in light of subsequent research and experience.

Chemical Resistance of Polytetrafluoroethylene

The maximum service temperature °C listed pertains to pressure piping systems and should not be exceeded. For drainage systems, the listed maximum service temperature °C may be exceeded in some cases. However, testing is recommended for pressure systems and/or drainage systems under actual operating conditions to determine material suitability when long term exposure to liquids is expected!

+ Resistant within the acceptable limits of pressure and temperature; the material is unaffected or only insignificantly affected.

O Conditionally resistant. The medium can attack the material or cause swelling.

- Not recommended. The material cannot be used with the medium at all, or only under special conditions.
