IntroductionRFI and EMI shielding and absorbing materials, such as 5-CN4190-1, provide protection to operative equipment and personnel from the transmission of radio frequency interference (RFI) or electromagnetic interference (EMI). The 5-CN4190-1 is a heavy-duty foam specially designed to shield these types of radiation or signals from outside sources.Application FieldThe 5-CN4190-1 is suitable for a wide range of applications, such as electronics and industrial noise reduction. It has been used in a variety of applications including radio and TV broadcasting, electrical wiring, military applications, laboratory research, cell phone protection, and medical technology. The foam is also used to provide protection from electric or magnetic fields in computer rooms or even for soundproofing and absorbing acoustics within conference rooms and other sound-sensitive areas.Working PrincipleThe 5-CN4190-1 works by preventing the transmission of electromagnetic radiation (EMR) through its specialized cells. The material consists of a network of interlinked closed cells. This makes it suitable for blocking EMR through absorption rather than simply reflecting the waves away. As the EMR passes through the material, the closed cells absorb the energy and dissipate it. This ensures that the effects of the radiation are reduced and the material remains effective over time.The material is also highly effective at preventing the transmission of RFI. This type of radiation is more likely to penetrate buildings due to its longer effective range and lower frequency. The 5-CN4190-1 is specially designed to absorb the RFI and potentially interfere with any signals that are sent. This diminishes any potential disruptions and interference signals that could be causing problems in a given area.The material also offers an additional layer of protection from the transmission of ElectroStatic Discharge (ESD). ESD can be particularly damaging to delicate electrical elements within an area. The 5-CN4190-1, with its closed cell structure, provides extra insulation and absorbs any potential discharges. This can prevent any surges or spikes from disrupting the circuit and damaging the electronic equipment.ConclusionThe 5-CN4190-1 is a highly effective solution for shielding and absorbing both EMI and RFI based radiation. The material is highly efficient in its ability to absorb and dissipate EMR and RFI thereby preventing the transmission of interference signals. It is also effective in protecting from potential electrostatic discharge that can be harmful to electrical equipment. As such, it is a highly versatile solution that can be used effectively in a variety of applications.
