RF interference and electromagnetic interference (EMI) can severely degrade the performance of critical equipment, regardless of whether it’s in a medical facility, an industrial laboratory, or a military installation. Shielding and absorbing materials are used to absorb or divert electrical fields and thereby reduce the risk of operational failures and excessive emissions. This article will examine the application field and working principle of 5-1120-1S, a shielding and absorbing material designed for applications where a high level of EMC compliance is required.

Application Field

5-1120-1S is designed for a wide range of EMC applications, including: medical equipment, military systems, aircraft, automobiles, communications systems, computers and peripherals, radar systems, industrial control systems, and space applications. It is also suitable for high-frequency RF shielding and absorption in areas where sensitive test and measurement systems are in use. 5-1120-1S is a broadly appropriate choice for both general-purpose EMC performance and frequency-selective filtration applications.

Working Principle

5-1120-1S is a combination of a conductive polymer/resin blended with granular and fiberglass-based absorbers. The conductive polymer/resin applied on the surface effectively reflects RF waves, thereby minimising radiation from sensitive electronic components and enclosures. The granular and fiberglass-based absorbers provide an absorbing medium for conducted and radiated, EMI interference, increasing the overall effectiveness of the system. By using this combination of conductive and absorptive materials, 5-1120-1S is able to offer a high level of EMC compliance within a wide operating frequency range.

Additional Features

In addition to its excellent EMC compliance and wide operating frequency range, 5-1120-1S has several additional features which make it particularly suitable for a variety of applications. Most notably, it is extremely flexible, making it easy to apply to complex shapes. It is also lightweight and resistant to solvents, chemicals, and temperature extremes. Finally, it has excellent adhesion to a wide variety of substrates, including painted surfaces, plated surfaces, and conductive coatings.

Conclusion

5-1120-1S is a shielding and absorbing material designed for applications which require a high level of EMC compliance. It is suitable for a wide range of applications, including medical equipment, military systems, and industrial control systems. Its combination of conductive and absorptive materials enables it to offer a high level of EMC compliance within a wide operating frequency range. Furthermore, it is lightweight, flexible, and resistant to solvents, chemicals, and temperature extremes, making it an ideal choice for a variety of applications.
