| Abstract: | The effects of silica type and content, vinyl silicone oil of different viscosity and cross linking density on mechanical properties and resistance to tracking performance of liquid silicone rubber were studied. Results of research showed that increasing the amount of silica and the viscosity of vinyl silicone oil could help to improve the mechanical properties of silicone rubber. On the other hand, adding VMQ silicone resin to increase the cross linking density could effectively improve the tracking performance to meet the special requirement of silicone rubber in electricity industry. |
