Silicone rubber has excellent heat resistance, cold resistance, dielectric properties, ozone resistance and atmospheric aging resistance.
The outstanding performance of silicone rubber is its wide use temperature, which can be used for a long time at -60℃ (or lower temperature) to +250℃ (or higher temperature).
However, silicone rubber has poor mechanical properties such as tensile strength and tear strength, and its physical and mechanical properties are not as good as most synthetic rubbers at room temperature.
In addition to nitrile silicone and fluorosilicone rubber, general silicone rubber has poor oil resistance and solvent resistance. Therefore, silicone rubber is not suitable for use under ordinary conditions.
But it is very suitable for many specific occasions.
