Abstract :
This study was carried out to investigate the influences of low materials (the vinyl content of polydimethylsiloxane and reinforcing silica) on the electrical and mechanical properties of silicone rubber for high voltage insulation. When the content of vinyl group was increased, cross-linking density and hardness were increased and tensile strength, volume resistivity and tracking resistance were improved. The mechanical properties and electrical properties of silicone rubber reinforced with fumed silica were higher than these of silicone rubber reinforced with precipitated silica. It was found that electrical and mechanical properties of silicone rubber were influenced by the water contents of silica very much.
