The 5-1267-3/4-3R is a high performance shielding material consisting of several layers of expandable graphite and elastomer composite. It is designed for optimal EMI absorption and RFI shielding performance. The composite material is composed of several layers of elastomer material and expandable graphite, layered in a dimensionally stable manner. Each material layer plays a critical role in achieving the desired performance characteristics of the material.

Application Field

5-1267-3/4-3R shielding materials are primarily used to shield against electro-magnetic interference (EMI) and radio frequency interference (RFI), from low to high frequencies. Typical applications include automotive, aerospace, military, medical, industrial and consumer electronics. It is also used to protect sensitive electronic equipment from external electromagnetic noise, which can affect data integrity and performance.

Working Principle

The 5-1267-3/4-3R shielding material is designed to reduce the intensity of electromagnetic interference (EMI) and radio frequency interference (RFI), by absorbing and reflecting the energy. The absorbent elastomer layer of the composite material absorbs the energy from the wave. The second layer, consisting of expandable graphite, reflects the energy away from the protected area, while providing a more evenly distributed EMI/RFI absorption because of its high electrical conductivity.

This makes it ideal for use in a variety of applications where high quality EMI/RFI performance is required, such as consumer electronics, automotive, aerospace, military, medical and industrial applications. Additionally, the composite material is dimensionally stable, making it easy to install, and it offers superior thermal and acoustic insulation.

Conclusion

The 5-1267-3/4-3R composite material is a high performance shielding and absorbing material designed to shield against EMI and RFI. The material consists of several layers of elastomer material and expandable graphite layered in a dimensionally stable manner, providing optimal EMI absorption and RFI shielding performance. The material is ideal for use in a variety of applications requiring high quality EMI/RFI performance, such as consumer electronics, automotive, aerospace, military, medical and industrial applications.
