Linde - Conductive Silicone Sealing Ring
The conductive silicone sealing ring is a specialized rubber component designed to offer both excellent electrical conductivity and strong sealing capabilities. It consists of silicone rubber as the base material, integrated with conductive fillers like ethylene carbon black, graphite, copper, and silver powders. These materials ensure the O-rings and various ring models maintain robust electrical performance, making them essential in applications requiring EMI/RFI shielding. The product range includes several configurations such as O, U, V, Y rings, and flat gaskets to cater to multiple environments. Notably, these components can endure temperature fluctuations from -60 to 200℃ without significant degradation, demonstrating durability in both high and low thermal conditions. This adaptability, coupled with compliance to standards like UL94 V0 and RoHS, makes them suitable for use in electronics, automotive, and industrial applications, including LCDs, LEDs, IC chips, and PCBA assemblies.Conductive silicone sealing ring mainly refers to silicone sealing ring, which has excellent conductivity. Usually, rubber products are conductive because carbon black is added to the raw material when adding auxiliary materials. Carbon black is conductive, but the conductive current also has strengths and weaknesses. Silicone conductive O-rings have excellent electrical conductivity. Product models include conductive silicone O-ring, conductive silicone U-ring, conductive silicone V-ring, conductive silicone Y-ring, conductive silicone rectangular sealing ring, conductive silicone sealing ring, conductive silicone flat gasket sealing ring, etc.

According to the type and processing method of the basic rubber, high-temperature vulcanized conductive silicone rubber and room-temperature vulcanized conductive silicone rubber can be made, as well as pressure-sensitive conductive silicone rubber, anisotropic conductive silicone rubber and low-temperature conductive silicone rubber.
Compared with general conductive rubber, conductive silicone rubber has the advantages of small volume resistivity, low hardness, high and low temperature resistance (-60~200℃), anti-aging, good processing and manufacturing performance, and is particularly suitable for manufacturing.
In recent years, with the rapid development of electronic technology and instrument industry, the improvement and development of conductive silicone sealing ring have been promoted, and many new processes and new varieties have emerged. For example, during the vulcanization process, normal-pressure hot air thinning of conductive silica gel occurs instead of traditional high-temperature addition vulcanization (peroxide thinning). In terms of product performance, high tear-resistant conductive silica gel appears, and in Silicone rubber has a metal powder added to it and the pressure-receiving part is opened, while uninsulated pressure-sensitive silicone rubber uses pressure. Therefore, the application of conductive silicone sealing ring is becoming more and more widespread.
