Graphite nickel plated conductive silicone rubber: key material for EMI shielding in AI servers, new energy vehicles, and high-end electronic devices

1、 Why do AI servers and new energy vehicles increasingly require high-performance EMI shielding materials?

In recent years, the development of AI big models, high-performance computing, new energy vehicles, and intelligent equipment has made the processors, memory, power modules, and high-speed communication interfaces inside electronic devices increasingly dense. As the operating frequency of devices continues to increase, the problems of electromagnetic radiation and electromagnetic crosstalk become more apparent. If electromagnetic interference cannot be effectively controlled, it will not only affect the stable operation of the equipment, but may also lead to signal distortion, data transmission errors, and even affect the product's EMC certification.

Although traditional metal shielding components have good conductivity, they often struggle to balance flexibility, sealing, and assembly efficiency in complex structures, long-term vibrations, and high sealing requirements. Graphite nickel plated conductive silicone rubber is widely used in this demand context. It uniformly disperses highly conductive graphite nickel plated particles in a silicone rubber matrix, forming a stable conductive network while maintaining excellent flexibility. It can simultaneously achieve the three functions of conductivity, EMI shielding, and environmental sealing, making it a widely used EMI gasket material in modern electronic devices.

2、 What are the core advantages of graphite nickel plated conductive silicone rubber?

Compared to ordinary conductive rubber, graphite nickel plated conductive silicone rubber not only has excellent shielding performance, but also meets the reliability and long-term stability requirements of modern electronic devices.

The material has low volume resistance and can quickly form stable conductive paths, achieving efficient electromagnetic shielding over a wide frequency range. At the same time, silicone rubber itself has excellent elastic recovery ability, which can maintain stable contact pressure even in long-term compression, repeated opening and closing, and complex vibration environments, thus avoiding the problem of traditional metal spring plates deteriorating shielding performance due to fatigue.

In addition, the product also has good high and low temperature resistance, moisture and heat resistance, and aging resistance, which can adapt to complex application environments such as new energy vehicles, battery management systems, military electronics, aerospace, etc. For electronic devices that require long-term operation, this stable and reliable material can effectively reduce the risk of EMI leakage and improve the overall reliability of the machine.

Advanced Institute Technology can customize material hardness, conductivity, compression deformation, shielding effectiveness, and operating temperature range according to different product requirements, providing customers with more matching solutions.

3、 Diversified product structure to meet the shielding needs of different devices

For different product structures, graphite nickel plated conductive silicone rubber can be processed into various forms, including conductive rubber plates, conductive sealing rings, conductive sealing strips, conductive gaskets, conductive rubber hoses, and various shaped EMI shielding components, which can meet the installation needs of different equipment.

At present, the product has been widely used in:

• AI server cabinet and GPU server shielding and sealing
• New Energy Vehicle BMS Battery Management System
• 5G communication base station and RF equipment
• Military electronics and aerospace equipment
• Medical electronic equipment EMI protection
• Industrial robots and automation control systems
• Precision testing instruments
• UAV flight control system
• IoT intelligent terminal

For different application environments, the company can also provide different conductive filler systems and products with different compression recovery properties to balance conductivity, mechanical properties, and service life.

4、 Advanced manufacturing processes ensure product consistency

The performance of conductive silicone rubber products depends not only on the conductive filler, but also on the material formula and production process.

Advanced Institute Technology has mature research and development capabilities for conductive composite materials. Through highly uniform dispersion processes, graphite nickel plated conductive particles form a continuous and stable conductive network in the silicone rubber matrix. Simultaneously combining precision mixing, continuous rolling, compression molding, and automated testing processes, effectively controlling material resistivity, hardness, compression set rate, and dimensional consistency.

According to the different needs of customers, the company can provide products with different thicknesses, cross-sectional shapes, and sizes, and support rapid sampling and mass production, providing stable and reliable EMI shielding solutions for various high-end electronic devices.
