Measurement of Rubber Elasticity and Correlation with Seal Life

Two new methods will be presented to measure rubber and seal elasticity - Recovery from Bending (RFB) and Loss of Seal Interference (LOSI). It will be demonstrated, the kinetics of rubber elasticity change during immersion in oil with aeration and oil change for different rubber compounds as NBR, HNBR, ACM, AEM, FKM and VMQ. Using the kinetics of Recovery From Bending, the estimation of seal life can be done.
