This specification covers a tetrafluoroethylene/propylene rubber (FEPM) in the form of molded rings.
These rings have been used typically as static sealing rings for continuous use from -5 to +232 degrees C (+23 to +450 degrees F) in dry air, in hydraulic fluids, synthetic lubricants, and high pH chemical decontamination fluids, but usage is not limited to such applications.
