Perfluoroelastomer (FFKM)
FFKM is a thermoset elastomer or rubber material. It has the highest density and the lowest ductility among rubber materials. The graph bars on the material properties cards below compare FFKM to other rubber materials (top) and the entire database (bottom). A full bar means this is the highest value in the relevant set. A half-full bar means it's 50% of the highest, and so on.
