“…Most of the findings of the earlier study were in agreement with the literature. [2][3][4][5][6][7][8][9][10][11][12][13][14][15] It also paved way for EPDM based insulation to be used in large CRMC as huge benefits were obtained in terms of reduction in weight, improved low temperature flexibility, improved aging, and erosion resistance. [16][17][18][19][20][21][22][23][24] Curing of EPDM insulations used for comparative characterization was carried out at 120 C for a duration of 6 h, fixed with the help of achieved mechanical properties as Rheometer curves were progressive at 120, 140, and 150 C temperatures even for long duration.…”

Two potential formulations of sulfur cured ethylene propylene diene terpolymer (EPDM) insulation were characterized against the proven insulation based on nitrile rubber (NBR) in the earlier study. Unlike the proven insulation, the cure behavior exhibited by sulfur cured EPDM is quite different in that, the rheometer curves exhibit marching behavior even at elevated temperature for longer duration (160 C for 7 h; most severe condition). This warranted extensive cure study at different temperatures for varying durations in order to determine the optimum cure condition. The methodology adopted to find out the optimum cure condition and corroboration of the same in terms of instrumental techniques (differential scanning calorimetry, thermogravimetric analysis, and Fourier transform infrared), which are quite interesting, are discussed in this article.
