There are many types of silicone rubber used in the aviation industry. According to its vulcanization method, it can be divided into room temperature vulcanized silicone rubber (including condensation silicone rubber and addition molded silicone rubber) and thermally vulcanized silicone rubber. In addition, there are unvulcanized silicone rubber. According to its functions, it can be divided into: oil-tight, air-tight, water-tight and other fluid sealing materials, vibration isolation, vibration absorption and other vibration and noise reduction materials, heat conduction, heat insulation, heat insulation and other materials, electrical conductivity, magnetic conductivity, wave absorption and other electromagnetic shielding and Stealth materials, fire-retardant, fire-proof and other safety protection materials, etc. Therefore, this article takes the vulcanization method of silicone rubber as the main line and introduces the application of silicone rubber in the aviation industry.
