Chemical Compatibility
Certain combinations of chemical environments, temperature, and stress can adversely
affect parts made from thermoplastic resin. For this reason, material which may come in
contact with the 9457 unit should be carefully evaluated under end-use conditions for
compatibility. Also, follow the use and compatibility recommendations of the material
manufacturer. Table Chapter 6 -1 lists general chemical compatibility guidelines for the
9457.

Chemical Class Effects
Acids No effect under most common conditions of concentration and temperature.
Alcohols Generally compatible at low concentration and room temperature. Higher
concentrations and elevated temperatures result in etching and attack evidenced by
decomposition.
Alkalis Generally compatible at low concentration and room temperature. Higher
concentrations and elevated temperatures result in etching and attack evidenced by
decomposition.
Aliphatic
Hydrocarbons Generally compatible
Amines Surface crystallization and chemical attack. Avoid.
Aromatic
Hydrocarbons Partial solvents and severe stress cracking agents. Avoid.
Detergents and
Cleaners Mild soap solutions are compatible. Strong alkaline materials should be avoided.
