Problems solved by technology

[0002] Fluorine rubber is a kind of synthetic polymer elastomer in which carbon atoms in the main chain or side chain are connected with fluorine atoms. It has good high temperature stability, medium resistance, physical properties and electrical insulation. It has been widely used in modern Aeronautics, aerospace, rockets and other cutting-edge science and technology fields, but fluorine rubber also has the defects of large permanent deformation and poor heat resistance. At the same time, it is used in cables with defects of insufficient flame retardancy, aging resistance and heat resistance. , which limits its application
