The electrical properties of silicone gel due to curing condition

In order to investigated the electrical properties of silicone gel due to the curing condition, volume resistivity and dielectric strength are investigated. Some samples made under several different curing conditions are experimented. The relationship between dielectric strength and electrode distance is investigated as well in this paper. The external 60 Hz; 3 kV/sec AC voltage is applied to the specimen until the dielectric breakdown occurs. It is proved that the electrical properties of specimen cured at 170/spl deg/C, 60 minutes and 120 minutes are superior to the others in the experimental result.
