Chemical Compatibility - Xycom 9462 System Manual

Chemical Compatibility

Certain combinations of chemical environments, temperature, and stress can adversely af-
fect parts made from thermoplastic resin. For this reason material which may come in
contact with the 9460/9462 unit should be carefully evaluated under end-use conditions for
compatibility. You should also follow the use and compatibility recommendations of the
material manufacturer. The following table lists general chemical compatibility guidelines
for the 9460/9462.

No effect under most common conditions of concentration and tem-
perature.
Generally compatible at low concentration and room temperature.
Higher concentrations and elevated temperatures result in etching
and attack evidenced by decomposition.
