RFI and EMI shielding and absorbing materials are designed to function as barriers or filters to keep out disruptive electromagnetic radiation. Many types of materials, from steel and copper to conductive rubber and fiberglass, are effective for shielding and absorbing EM radiation. One such material is CN 3190 X 1”, which can be helpful in mitigating both interference and potential safety hazards across a wide range of applications.

CN 3190 X 1” is composed of conductive carbon-rich black bitumen layer, and aluminum foil. The bitumen layer acts as a barrier against RFI and EMI radiation while deflecting any heat generated by the material. The combination of bitumen’s carbon layer and aluminum foil provides a high level of shielding efficiency — 95 dB at 1 GHz/60 Hz, according to tests from accredited laboratories. Additionally, CN 3190 X 1” can be customized for specific customer needs.

Applications of CN 3190 X 1” shielding and absorbing materials vary widely, from use in cell towers and military equipment to aircraft and medical devices. The RFI/EMI shielding contributions of CN 3190 X 1” help protect a variety of different electronic systems from potentially detrimental impacts caused by radiation. At the same time, its insulating properties maintain the structural integrity of these systems, as well as making their components easier to handle and install.

CN 3190 X 1”’s electromagnetic shielding/absorbing capabilities and insulation strength are balanced to meet the realities of an environment with interference from external electromagnetic sources. Shielding materials help reduce crosstalk between electronic components, improving signal fidelity. They also provide the necessary protection from electromagnetic pulses (EMP) generated from computers, cell phones, and other electronic devices. Further, the bitumen layer helps dampen unwanted joint resonance, ensuring signal paths are clear and not impacted by extraneous noise from other components.

Given its strength and shielding efficiency, CN 3190 X 1” is suitable for a variety of RFI/EMI applications. Examples include cell towers, which may produce radiation that can cause electrical interference in user’s devices; and industrial motors, with their gears and other moving parts which may produce radio noise. By coating CN 3190 X 1” across these surfaces, any interference can be drastically reduced. Additionally, CN 3190 X 1” can be used in places where excess heat might be generated, such as electrical equipment cabinets, to dispel thermal energy from components.

In summary, CN 3190 X 1”’s 95 dB shielding efficiency at 1GHz/60Hz makes it suitable for a wide range of RFI/EMI applications. Its tightly sealed design further enhances its shielding ability, and its insulation properties make it an excellent choice when needing to control excess heat or ensure electrical safety. Ultimately, CN 3190 X 1” is a versatile material that can be used to protect and improve the performance of a variety of different systems and applications.
