Average corrected creep strain for PEEK-OPTIMA as a function of a linear and b logarithmic time. The total creep strain after 2000 hours in a 37°C aqueous environment at an applied stress of 10 MPa was on average less than 0.1%. For reference, the corrected creep strain for standard PEEK polymer (450 G) in a dry, 23°C environment is also plotted [34]
