Hydrated Silicone Dioxide for Silicone Rubber
Silicone rubber has high heat resistance, excellent cold resistance, ozone resistance, atmospheric aging resistance and excellent electrical insulation In addition, silicone rubber has low water absorption and can be stored in wet places for a long time It can be widely used in aerospace, military, electrical, medical and other departments. However, silicone rubber molecules have a spiral structure and are highly flexible The intermolecular force is weak and it is difficult to crystallize. The tensile strength of raw rubber after vulcanization does not exceed 0.34 mpa This greatly limits its application. Adding reinforcing filler is the main means to adjust the physical and mechanical properties of silicone rubber. Only adding reinforcing material silicone rubber can have practical value ". In order to reduce the production cost of silicone rubber products, the market began to use ultra-fine precipitated silica to partially replace gas-phase silica, and great breakthroughs have been made in application research Therefore, the demand for silica by ultra-fine precipitation method for silicone rubber is increasing rapidly.
