Description: Perfluoroelastomer (FFKM) O-rings

Perfluoroelastomer (FFKM) is most commonly known by the DuPont trade name Kalrez®. Perfluoroelastomer compounds offer the widest range of chemical and solvent resistance as well as very high operating temperatures (up to 428° F / 220°C).

The price of products made from Perfluoroelastomers tend to be very high due to the raw material cost, so this polymer is used for specialty applications only. The low temperature range is only -20° to +20°F depending on the compound. Thermal expansion needs to be considered when using Perfluoroelastomers at elevated temperatures.
