Effects on Thermal Aging and UV-A Aging on Dielectric Performance of High Temperature Vulcanized Silicone Rubber

High temperature vulcanized silicone rubber (HTV-SIR) was aged at 200 °C and under UV-A radiation. The dielectric parameters increased more after thermal aging than that after UV-A aging in 0.4-1.8 THz. Results of Fourier transform infrared spectroscopy showed that the side chains of HTV-SIR cracked after thermal aging. The content of Si-O increased slightly, indicating the cross-linking degree in...
