WebOct 2, 2024 · Full size image. After hot air aging, the silicone rubber’s Si-CH 3 absorption peak intensity was somewhat lower. Due to the fact that the binding energy of Si–C in silicone rubber is lower (301 kJ/mol) than that of Si–O (447 kJ/mol) and C–H (414 kJ/mol). Si–CH 3 is hence more readily obliterated during hot air aging.
