Abstract

Accelerated thermal aging conditions of polymeric materials were studied by Kissinger equation with TGA analysis. The activation energy was obtained from the slope of straight line of each specimen at the different TGA heating rate. Estimating activation energy from Kissinger equation was acquired, and the resulting calculation showed that 3.59, 3.0, 3.86, 3.73 for the PEEK, polyimide, polysulfone and Viton, respectively. The studied polymeric specimens are used for electrical penetration assembly in nuclear power plant. Accelerated aging time and temperature were also determined corresponding to actual service temperature and 41 years.
