(1) High and low temperature resistance
Organosilicon rubber exhibits excellent mechanical properties in high-temperature environments (above 200 ℃), while still possessing a certain degree of toughness and elasticity. The glass transition temperature (Tg) can be as low as -70 ℃. In general, the working temperature of silicone rubber is between -100 ℃ and 350 ℃. It can withstand instantaneous high temperatures of thousands of degrees, so it is often used to make heat-resistant coatings, such as in the aviation industry.

(2) Electrical insulation
Organic silicone rubber has good insulation properties, and after combustion, the generated silica remains the insulating material. In addition, silicone rubber is less prone to burning during arc discharge due to its low carbon atom number in its structure and its reinforcing filler, white carbon black, making it suitable for high-pressure applications.

(3) Physiological inertia
The surface of silicone rubber is hydrophobic, so the physical properties decrease slightly in humid environments. Poor adhesion can serve as a barrier. And it itself is non-toxic and odorless, without harm to human health, and can only react slightly with the body, which creates its excellent physiological inertia. At the same time, it is also very superior in terms of physiological aging performance.
