In 1960s, China's aviation industry urgently needed a kind of arc resistant silicone mold plastic which can withstand strong current and high voltage for making micro switches. Beijing Research Institute of chemical industry has successfully developed silicone resin which is directly hydrolyzed from methyltrichlorosilane and made into arc resistant mold plastic with asbestos filler, which has solved the urgent need of aviation industry. The material was transferred to Shanghai resin factory for production. However, users still need this kind of material, so they have to ask for help from Chenguang Chemical Research Institute, which moved to Sichuan Province. In order to meet the urgent needs of users, Wu Shengquan et al. Of the Institute used the hydrolysis condensation route from methyltriethoxysilane as the starting material to prepare the silicone resin for molding plastics with satisfactory performance, so as to solve the urgent needs of users.
