Abstract
This research measured the dielectric properties of silicone rubber with various hardness in 100 Hz~3 MHz, <TEX>$30{\sim}170^{\circ}C$</TEX> conditions. When the hardness increases from 65 degree to 75 degree, the dielectric loss increased within frequency range of 100 kHz~3 MHz and was a little change in dielectric loss within temperature range of <TEX>$90^{\circ}C{\sim}170^{\circ}C$</TEX>. Thermogravimetric Analysis (TGA) showed the weight change rate increased a little while heated until <TEX>$800^{\circ}C$</TEX>. Scanning Electron Microscope (SEM) measurement showed that Aluminium Trihydroxide(<TEX>$AlOH_3$</TEX>) which acts as a reinforcement agent reduced the size of the particles as the hardness increased.
