Isothermal Weight Loss and Life Expectancy Curves of Polymers in Air

reportActive / Technical Report | Accession Number: ADA070541 | Open PDF

Abstract:

Sixty-five polymers have been subjected to isothermal aging in air for up to 200 hours at one or several temperatures of 500, 550, 600, 650, 700, and 750 F and the weight loss-time curves plotted. The data have been used to obtain life expectancy plots for 20 and for 30 weight loss.
