Silicone rubber is a specialty rubber formed by adding crosslinking agents, reinforcing fillers, and other additives to a linear polyorganosiloxane-based polymer, followed by compounding and vulcanization. Silicone rubber's unique physical and chemical properties have made it widely used in various fields.

The main chain of silicone rubber consists of alternating silicon and oxygen atoms, with silicon atoms typically connected to two organic groups. This structure gives silicone rubber many excellent properties. Firstly, silicone rubber has high heat resistance and excellent cold resistance, maintaining its elasticity under extreme temperature conditions. Secondly, silicone rubber exhibits excellent electrical insulation properties, with minimal impact on its electrical performance when subjected to temperature and frequency changes or moisture. Additionally, silicone rubber has outstanding resistance to ozone aging, thermal aging, UV aging, and atmospheric aging, as well as good oil and solvent resistance.

Silicone rubber is particularly widely used in the electrical industry. It can be used to manufacture insulating layers for electrical equipment such as wires and cables, transformers, and motors. It is also used to make sealing parts for electronic and electrical products, such as waterproof seals for mobile phones and cameras. Furthermore, silicone rubber is used in cable accessories, composite insulators, anti-pollution flash coatings, and thermally conductive silicone rubber.

In general, silicone rubber plays an important role in various fields such as electrical, electronics, medical, and construction due to its excellent properties.
