For conductive silicone rubber, the most important performance, including the following points:

1. Volume resistivity: to measure the electrical conductivity of conductive silicone rubber, as a conductor, the volume resistivity of conductive silicone rubber should be less than 10^3 ω •cm, the smaller the volume resistivity, the better the electrical conductivity.

2. Mechanical properties: Mechanical properties of conductive silicone rubber, mainly including tensile strength, elongation at break, tear strength, Shore hardness and compression permanent deformation.

3. Aging resistance: aging resistance is a very important performance of conductive silicone rubber, which is directly related to the stability and service life of the product.

4. Shielding efficiency (dB) : shielding efficiency is a very important indicator of electromagnetic shielding materials, which is related to electrical conductivity. The stronger the electrical conductivity, the higher the shielding efficiency. Generally speaking, the shielding efficiency of conductive silicone rubber is greater than 60dB.
