Chemical Compatibility

Durlon® 9000 is the only filled PTFE gasket material that is approved for service with: Wet and Dry Chlorine, Sodium Hydroxide, Vinyl Chloride, Ethylene Dichloride, Sulfuric Acid and Oxygen making it the clear Chlor-Alkali Industry choice.


Chemical resistance of the gasket material is important because without it, the other properties of the gasket are irrelevant. It is also important to keep in mind the effect temperature has on chemical resistance.

A chemical resistance chart can be a helpful guide. This information is available but it must be remembered that most chemicals become more reactive at higher temperatures. This must always be considered when selecting the gasket.

In some instances it is only prudent to consider field testing in a controlled application and we encourage this. Samples are available for such purposes. For samples please request, fill out and submit a sample request form.
