The main purpose of this paper is to investigate the time dependency of rubber viscoelastic characteristics at various shape factors (SF) and compression percentages (%), namely Compressive Stress Relaxation (CSR) and Retaining Sealing Force (RSF). Results from nonlinear Finite Element Analysis (FEA) were found corresponding with the static CSR data, which could be used for estimating long term CSR effects of particular products with similar SF and compression % and operation environments.
