What is conductive seal silicone rubber?

Conductive silicone rubber is vulcanized by adding conductive filler, crosslinking agent and so on. Commonly used conductive fillers are carbon black, carbon fiber, superconducting electric carbon black, graphite, copper powder, silver powder, aluminum powder and so on.

Compared with general conductive rubber, conductive silicone rubber has the advantages of small volume resistivity, low hardness, high and low temperature resistance (-70 to 200℃), aging resistance, good processing and manufacturing process performance, especially suitable for the manufacture of conductive silicone rubber products with good conductivity, complex shape and small structure.

According to the different varieties and processing methods of the base rubber, it can be made of high temperature vulcanized conductive silicone rubber and room temperature vulcanized conductive silicone rubber, as well as pressure sensitive conductive silicone rubber, anisotropic conductive silicone rubber and low temperature conductive silicone rubber.

In recent years, with the rapid development of electronic technology and instrument industry, the improvement and development of conductive silicone rubber has been promoted, and many new processes and new varieties have appeared. For example, in the vulcanization process, the atmospheric pressure hot air vulcanization of conductive silicone rubber has appeared, instead of the traditional high temperature addition vulcanization (peroxide vulcanization); In the performance of the product, there are high tear resistance conductive silicone rubber and some metal powder added to the silicone rubber, the pressure part is conductive, and the pressure part is still insulated. Therefore, the application of conductive sealing ring silicone rubber is also more and more extensive.
