Our PEEK tubing does not have additives, but you may want to consider that PEEK is produced using phosphoric acid.  It is possible that some remnants of this acid may be present in our PEEK Tubing.

PEEK is not a fluoropolymer and is not impervious to all substances. It’s crucial to refer to the list of materials that can potentially harm PEEK to ensure that you’re not employing a solvent that could degrade it.
