This can be measured in two categories (a) short time exposure( a few hours) and (b) continuous use over a period of 5000 /20,000 hours. Our index compares material performance in category(b). after these periods there is a decrease in tensile strength compared to original value. As with all thermoplastics the maximum service temperature also depends on the duration and magnitude of mechanical stresses on the material in application.
