Elastomer: Tetrafluoroethylene/Propylene (FEPM) Hydraulic Fluid and Synthetic Oil Resistant 75 to 90 Hardness
This specification covers two classes (durometers) of tetrafluoroethylene/propylene rubber (FEPM) in the form of extrusions, sheet, strip, and molded shapes. These products have been used typically for components requiring continuous operation in dry air, hydraulic fluids, and synthetic engine oils at temperatures from -5 to +232 ° C (+23 to 450 ° F) or in high pH chemical decontamination solutions, but usage is not limited to such applications.
Rationale: This revision eliminates corrosion and weathering requirements, modifies periodic testing duration and removes “or equivalent” from hardness requirement. It also incorporates the format of the most current AMS3XXX template.
