KnitMesh Technologies’ Mesh-Covered Elastomer Cores are engineered to provide exceptional protection against EMI and RFI, offering a reliable shielding solution for electronic enclosures with uneven seams and situations where low closure forces are necessary. The flexible central core effectively fills in the gaps, ensuring a seamless connection between mating surfaces, particularly beneficial for frequently accessed panels and doors that are assembled and disassembled.

Adapting to varying shielding requirements, KnitMesh Technologies offers a range of options for shielding effectiveness. A single layer of knitted wire mesh provides moderate shielding, suitable for many applications. For higher levels of attenuation, a double cover is recommended, and additional layers of knitted wire mesh can be added if more extensive shielding is required.

Notably, KnitMesh Technologies manufactures Mesh-Covered Elastomer Cores with a diverse range of cover materials, catering to different environmental and application needs. Additionally, the availability of multiple core materials such as neoprene sponge, silicone sponge, silicone tube, and EPDM further underscores the versatility and adaptability of these cores.




Mesh-Covered Elastomer Cores are utilised in electronic enclosures and compartments within aircraft, satellites, and other aerospace vehicles. They provide effective shielding against EMI and RFI, ensuring the reliable performance of sensitive electronic systems.

Automotive and Transportation


In the automotive industry, Mesh-Covered Elastomer Cores are used to shield electronic components and systems from EMI and RFI. This is important for ensuring proper functioning of critical systems such as engine control units, navigation systems, and entertainment systems.



Mesh-Covered Elastomer Cores are employed in telecommunications infrastructure, including base stations, communication cabinets, and data centres. They provide EMI and RFI shielding, reducing signal interference and improving the performance and reliability of communication equipment.

Medical Devices


In medical devices and equipment, EMI and RFI can disrupt the accurate functioning of sensitive electronic components. Mesh-Covered Elastomer Cores are used to shield medical equipment such as diagnostic devices, MRI machines, and surgical tools.

Electronics and IT


Mesh-Covered Elastomer Cores are commonly used in electronic enclosures, cases, and racks for various devices like computers, servers, switches, and routers. By providing effective EMI and RFI shielding, they help maintain the integrity of electronic circuits and improve overall performance and reliability.

Industrial Equipment


Mesh-Covered Elastomer Cores are also utilised in industrial equipment and machinery where EMI and RFI can disrupt the functioning of control systems and sensitive electronics. They provide shielding for automation systems, robotics, manufacturing equipment, and other industrial applications.

Understanding EMI and RFI

EMI refers to the phenomenon where electromagnetic energy disrupts the normal functioning of electronic devices and systems. This interference can originate from various sources such as power lines, electronic devices, radio transmitters, and even natural occurrences like lightning strikes. The consequences of EMI can manifest as noise, disturbances, or signal degradation, leading to compromised functions and unreliable performance of electronic equipment.

RFI, a subset of EMI, specifically relates to interference caused by radio frequency signals. When signals emitted by radio transmitters or wireless devices interfere with the reception or transmission of signals in electronic equipment, the result is impaired performance and compromised functionality. Devices such as radio receivers, telecommunications systems, and medical equipment are particularly susceptible to the effects of RFI.

Mesh-Covered Elastomer Cores are designed to provide effective shielding against EMI and RFI. They consist of an elastomer core that is covered with a conductive knitted wire mesh. The elastomer core provides flexibility and resilience, while the knitted wire mesh acts as a barrier to intercept and attenuate electromagnetic waves and radio frequency signals.
