www.sealseastern.comSep 24, 1998 · are key properties when considering the longevity of a seal. These values are functions of the stiffness of the material (and are time dependent). When considering a seal design, material stiffness is extremely important. The stiffness, or Young’s modulus (defined loosely), is a measure of how much spring force a rubber component will exert when
