Chemical Resistance



Important Note:

Whilst we try to ensure that this table is as accurate as possible we cannot guarantee that the data contained in the tables is accurate for all blends and grades of PES. In all cases the supplier of the material should be contacted to determine the exact chemical resistance of the material.
