The electrical insulation performance of silicone rubber vulcanized rubber changes little when it is damp, frequency changes, or temperature increases, and the silicon dioxide generated after combustion remains an insulator. In addition, silicone rubber has fewer carbon atoms in its molecular structure and does not use carbon black as a filler, making it less prone to burning during arc discharge and highly reliable for use in high-voltage environments.
Its corona resistance and arc resistance are excellent, with a corona resistance life 1000 times that of polytetrafluoroethylene and an arc resistance life 20 times that of fluororubber.

The surface energy of silicone rubber is smaller than that of most organic materials, and it has low moisture absorption. When immersed in water for a long time, its water absorption rate is only about 1%. Its physical properties do not decrease, and it has good anti mold performance. It does not bond with many materials and can act as a barrier. Silicone rubber is odorless, non-toxic, and has no adverse effects on the human body. It has a slight reaction with body tissues and has excellent physiological inertia and aging properties.

Compared with other polymer materials, silicone rubber has good breathability.

The unique molecular structure of silicone rubber endows it with excellent biomedical properties, as evidenced by the successful application of numerous animal and human experiments.
