PEEK™ (Polyetheretherketone)
Chemicals which interact with PEEK polymer are not pH dependent; rather,
interaction is more determined by other physical properties of the chemical(s)
in question. Not recommended for use with nitric acid; sulfuric acid; halogenated
acids, such as hydrofluoric, hydrobromic, and hydroiodic acids (hydrochloric
acid is approved for most applications); and pure halogenated gases. Additionally,
due to a swelling effect, be cautious in using the following solvents with
PEEK tubing: methylene chloride, THF, and DMSO.
