Conductive silicone rubber is a composite material composed of organic silicon compounds and conductive particles. Its characteristics mainly include the following aspects:
1. Excellent electrical conductivity
In the conductive silica gel, conductive particles such as silver-coated copper powder and nickel-coated graphite powder are evenly distributed so that these conductive particles are in contact with each other to achieve good conductive properties. Its resistivity is generally between 0.0020.1Ω·cm and can even be as low as 0.0051Ω·cm, depending on the type, content and distribution uniformity of the conductive particles.
Under a certain pressure, conductive silica gel can provide good conductivity and the suppression frequency can reach 40GHz, which gives it significant advantages in high-frequency electromagnetic environments.
2. Good sealing performance
Conductive silicone not only has good electrical conductivity, but also has excellent electromagnetic sealing and water vapor sealing capabilities. This characteristic makes conductive silicone widely used in situations that require a high degree of sealing, such as the packaging of electronic components and the sealing of cable joints.
3. High temperature tolerance
Due to the excellent properties of silicone rubber, conductive silicone rubber can maintain its material properties unchanged in high-temperature environments, and has the characteristics of high temperature resistance, low temperature resistance and oxidation resistance. This makes conductive silica gel have broad application prospects in areas that need to withstand high-temperature environments, such as automobile engine compartments and industrial furnaces.
4. Excellent processability and formability
Conductive silicone can be formed by molding, injection molding, spraying, etc., and can be processed according to the required size and shape. This property makes conductive silicone highly flexible and adaptable during the manufacturing process.
5. Diverse applications
Conductive silicon rubber is widely used in electronics, machinery, automobiles, and other fields. In the electronic field, it can be used as sealing materials, conductive gaskets, conductive glue, etc. for electronic components; in the mechanical field, it can be used as high-temperature sealing gaskets, rubber tubes, rubber parts, etc.; in the automotive field, it can be used Used as electromagnetic shielding materials, insulation materials and sealing materials for key automotive components.
6. Other features
Liquid conductive silicone also has the characteristics of curing at room temperature, fast curing speed, high production efficiency, and easy use. At the same time, it also has excellent properties such as waterproof, moisture-proof, mildew-proof, dust-proof, chemical media resistance, yellowing resistance, and weather aging resistance.
