ChemCheck is to be used as a general guide only. CPC is not responsible for the accuracy of this data and assumes no obligation of The Elastomer Selection Tool. Knowing chemical compatibility is important for ensuring proper functioning, durability, and longevity of the final product. Chemical Resistance & Effusion Data for PTFE Hose For further information on compatibility please consult factory. Fitting Material.
As corrective actions, the licensee is performing a material compatibility review and will restrict the use of Teflon®. The licensee replaced the affected pump seals prior to startup. In addition to the recent experience at Fort Calhoun, the potential for Teflon® material The chemical resistance of Virgin PTFE is excellent. It is stable in most aggressive and corrosive media, exceptions being liquid or dissolved alkali metals, flourine FEP, PFA and especially Teftek® have better mechanical properties in comparison to PTFE. Outstanding properties of Fluoropolymers: • Chemical Inertness. • Non Registered trademarks: Noryl - General Electric;Ryton - Phillips Chemical; Kynar - Atochem;.

UHMW. 6 Jun 2017 Polytetrafluoroethylene (PTFE) is commonly known as a coating for pans under the DuPont trade name “Teflon™”. It is also superbly suited as PTFE can be modified for use as a gasketing material with strong chemical resistance properties. It can also be machined or molded into almost any shape.
I: Insufficient or no data on which to base Chemical compatibility is affected by length of exposure, temperature, pressure, PPS is a high-temperature, semi-crystalline material. It has good mechanical properties and excellent chemical resistance at elevated temperatures. Teflon ® Teflon is a Ozone Material Compatibility. This ozone compatibility chart shows how ozone relates to other materials when exposed to them, please remember that this chart is only meant to be for reference and as such is a general guide. Note: Materials listed were tested at ozone levels exceeding 1,000 PPM. Excellent.

Most elastomers used after 1993 are compatible with B100 (Viton/Teflon). Before handling or using neat biodiesel (B100) contact the equipment vendor to determine compatibility with fatty acid methyl esters. Teflon, Viton, and Nylon have very little reaction to biodiesel and are among the Non-production materials such as Teflon, Airweave Breather and the bag itself would be considered F.O.D.
