Silicone rubber is a type of polymer elastomer that combines inorganic and organic properties. Its molecular backbone is composed of alternating silicon and oxygen atoms, with carbon-hydrogen or substituted carbon-hydrogen organic groups attached to the silicon atoms as side chains. This unique chemical structure gives silicone rubber many distinctive properties.

Silicone rubber exhibits excellent heat and cold resistance. It can operate at temperatures as low as -55°C, and with the introduction of phenyl groups, its low-temperature resistance can reach -73°C. Additionally, silicone rubber has outstanding heat resistance, capable of functioning at 180°C for long periods and enduring temperatures slightly above 200°C for weeks or longer, with instantaneous resistance to temperatures above 300°C.

Silicone rubber also boasts good electrical insulation, flame resistance, and ozone erosion resistance. Its electrical insulation is minimally affected by temperature and frequency changes or moisture, with excellent resistance to electrical corona and arcs. Furthermore, the inorganic components in silicone rubber ensure that even when it burns, the resulting non-flammable silicon dioxide ash retains insulating properties, providing unique fire-resistant performance beneficial for fire-resistant wires and cables.

In terms of applications, silicone rubber is widely used in electrical insulation, sealing materials, cable accessories, composite insulators, pollution-flashover preventive coatings, and thermally conductive silicone rubber. For instance, it is extensively applied in the manufacture of insulating layers for electrical equipment such as wires, cables, transformers, and motors. It is also used to make sealing components for electronic and electrical products, such as waterproof seals for mobile phones and cameras.

Overall, silicone rubber plays a significant role in modern life and industry due to its unique properties and diverse applications.
