O-type single extruded solid strip: Conductive silicone rubber sealing solution to assist in electromagnetic shielding of highly reliable electronic devices

Time:2026-07-29Number:97

1、 Why are more and more high-end electronic devices using conductive silicone rubber O-shaped solid strips?

In recent years, AI computing power centers, high-speed communication equipment, and new energy vehicle control systems have been continuously upgraded, and the number of PCBs, high-speed connectors, and RF modules inside the equipment has continued to increase. High frequency signals are prone to crosstalk and electromagnetic leakage.

Traditional ordinary rubber sealing strips can only achieve waterproof, dustproof, and shock resistance, but cannot effectively shield electromagnetic interference.

Conductive silicone rubber O-shaped single extruded solid strip combines bothSealed conductive shieldingThree major functions, which can form a continuous conductive circuit after equipment assembly and compression, effectively reduce electromagnetic leakage, and meet the increasingly strict EMC design requirements of modern electronic devices.

Based on years of research and development experience in conductive silicone rubber, Advanced Institute Technology can provide O-shaped conductive solid strips with different conductive systems (silver plated glass, silver plated copper, pure silver, nickel plated graphite, etc.) to meet different cost and performance requirements.

2、 The material properties determine the shielding effect and service life

The O-shaped single extruded solid strip uses silicone rubber as the elastic substrate, with uniformly dispersed high conductivity fillers inside, forming a stable and continuous conductive network after compression.

Compared to ordinary sealing materials, it has multiple advantages:

  • Excellent EMI electromagnetic shielding performance, capable of meeting the shielding requirements of high-frequency electronic devices;
  • Good compression rebound performance, maintaining stable sealing effect even after long-term compression;
  • Soft and easy to install, adaptable to complex grooves and irregular structures;
  • Resistant to high and low temperatures, ozone, and UV aging, suitable for long-term indoor and outdoor use;
  • Different conductive fillers can be selected according to application requirements to achieve a balance between performance and cost.

Advanced Institute Technology supports customization of different diameter specifications, hardness levels, and colors, and can also perform continuous extrusion processing according to equipment structure to improve assembly efficiency.

3、 Suitable for high reliability EMI shielding and sealing systems

With the development of devices towards high speed, high frequency, and miniaturization, conductive sealing materials have not only been used in traditional communication equipment, but have also widely entered multiple high-end industries.

Typical applications include:

  • Shielding and sealing of AI servers and data center cabinets;
  • Sealing of 5G base stations and RF communication equipment casings;
  • New energy vehicle BMS, electric drive controller, battery pack sealing;
  • Military electronics, radar equipment, and aerospace electronics;
  • Medical equipment control system and precision testing equipment;
  • Industrial automation control cabinets and intelligent manufacturing equipment.

In these applications, O-shaped single extruded solid strips not only block electromagnetic leakage, but also provide multiple protective effects such as dust, moisture, and shock resistance.

4、 Advanced Institute Technology provides professional customized conductive silicone rubber solutions

The performance of conductive silicone rubber sealing materials depends not only on the formula, but also on the material uniformity, extrusion process, and size control ability.

Advanced Institute Technology has established a mature production system for conductive silicone rubber and can provide customized development services according to customer project needs, including:

  • O-shaped single extruded solid strip;
  • Conductive silicone rubber sealing ring;
  • Conductive silicone rubber sheet;
  • Conductive silicone rubber shaped parts;
  • Conductive silicone rubber gasket and molded parts.

The product supports different conductive systems, size specifications, and compression performance designs, which can meet the diverse needs of EMI shielding and sealing materials in industries such as consumer electronics, communication equipment, industrial control, military equipment, and new energy vehicles.

In the future, with the continuous upgrading of AI computing platforms, high-speed communication networks, and intelligent manufacturing equipment, conductive silicone rubber sealing materials will play an increasingly important role in high-frequency electronic devices. Advanced Institute Technology will continue to deepen its expertise in the field of conductive composite materials, providing customers with more stable, reliable, and high-performance EMI shielding solutions.
