Chemically Inert
Fluoropolymer resins and PEEK are essentially chemically inert – they show little or no reactivity toward almost all commonly encountered substances. This feature of these polymers has long been one of their greatest assets. Zeus fluoropolymers and our other engineered products are ideal as transport for today’s highly volatile chemical compounds and exotic fluids.
The widespread acceptance within the chemical, environmental, aerospace, and medical industries is a testament to our polymers’ unique abilities to withstand and resist a wide variety of liquid and gaseous compounds. The minimal chemical activity of many of these polymers also makes them an excellent choice for pure water system and other potable liquid processes.
Exceptions
There are very few chemicals, such as molten alkali metals, turbulent liquid or gaseous fluorine, chlorine trifluoride, and oxygen difluoride that are known to react with fluoropolymers. To a lesser degree, halogenated organic chemicals may be absorbed by fluoropolymer resins. This absorption can sometimes be detected by a very slight change in weight of the polymer or slight swelling may possibly be observed. This phenomenon is less evident in FEP and PFA extrusions because they are relatively less permeable than PTFE extrusions.
Request Samples and Technical Information
To request samples of our fluoropolymers or other engineered tubing, or if you would like to discuss a specific application, we would like to talk with you. Zeus has a generous sample program making it easier than ever for engineers and designers to get stock and custom samples quickly.
The information in the Zeus eNewsletter, website, catalog, and other sources present and discuss generally accepted properties for non-pigmented virgin polymer resins from which Zeus fabricates its line of extruded products. Actual properties may change due to processing method, resin grade, extruded dimensions, and other variables. It is the end user’s responsibility to fully evaluate and test the fitness of the product for their specific application.
Additional technical support is available by contacting a Zeus technical account manager at 1-800-526-3842 or here.
Note: The chemical resistance of any polymer is defined largely by the chemical structure of the material and the strength of the weakest link in this structure.

Note: PTFE is attacked by some alkali metals (molten or in solution) and by some rare fluorinated compounds at high temperatures and pressures. Some organic and halogenated solvents are absorbed causing small dimensional changes but the effects are physical and also reversible.

While similar to PTFE, FEP has some distinct differences. It has a slightly higher coefficient of friction, lower continuous service temperature, and is more transparent than PTFE. FEP also has better gas and vapor permeability properties and excellent UV transmission.

This linear aromatic polymer is semi-crystalline and is widely regarded as the highest performance thermoplastic material currently available. PEEK™ polymer is widely regarded as a material with superb chemical resistance.
These tables provide general guidance for use with PEEK polymer and compounds. It has been shown that the performance of a component can depend on factors such as residual molding stresses and crystallinity level. Application-specific chemical resistance testing is essential for all components.
