Fluorosilicone Rubber (FVMQ)

FVMQ rubber is a thermoset elastomer or rubber material. It has the lowest tensile strength among rubber materials. In addition, it has a moderately high density and a fairly low ductility. The graph bars on the material properties cards below compare FVMQ rubber 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.
